Step 1: Take away 4 on both sides so there is an x and a number on one side
3 x + 4 = 19
-4 -4

Step 2: You subtract, and make your new equation.

3 x = 15

Step 3: Once you have your x and number on one side of the equation, you can now divide the number by it's x, and you will get your x.

3x = 15
÷3 ÷3

x = 5

I hope I helped out a bit.

Question = 3X+4=19
Solution = 3x=19 - 4
3x =15
x = 15/3
( 3x5=15 )
Answer = x = 5

2) Solution(with some explanation):-
3x + 4 = 19
then we will transpose 4 (also we can call it as the additive inverse of 4)
then, 3x = 19 - 4
= 3x = 15
then we will divide it by 3
then, x = 15/3 = 15/3 is 5
So, the x = 5
Done 👍✔️✔️

If you looked at the comments for further explanation or don't understand the vid, do this trick I learned,

2x - 5 = 17
2x = 17 + 5
2x = 22

2x = 22
2. 2

X= 11

Solution for 3x + 4 = 19:

By subtracting 4 on both sides,
3x = 15

By dividing 3 on both sides,
x = 5

Therefore, x is equal to 5.

Sir I have a question.
Q) The sum of 3 consecutive multiples of 11 is 363. I need to find these multiples.
A) let x = multiple of 11, then next multiple is x+11, next multiple is x+22; giving us equation of
x+x+11+x+22= 363
Solving it, we get x=110, x+11=121, x+22=132.
Alternative we can take multiple just before x, as in, x-11, x, x+11 giving us equation as
(x-11)+x+(x+11)=363 giving us x=121, x-11=110, x+11=132.
Doubt) Why can't we take two multiples before x? As in x-22, x-11 and x? Because when I do put it in equation, answers come out wrong, for eg x somehow=131.

3x + 4 =19
•like terms on the other side and constants on the other side
→3x=19-4
= 3x=15
= x = 15/3
=x = 5
Hence the x = 5

This guy has an ingenious talent of making simple things complicated.

[Madz]

It’s always the guys that have the best explanation 💀

[projackson]

That was easy, add negative 4 to both sides and then you get 3x=15, divide both sides by 3 and x = 5

[alexamelchor]

Another way to js solve this is to grab a calculator and replace the X with a number that will get you to 17. For ex, 2(11)-5=17 will give u 11 . As u can see I just replaced the X with a 11 in order to get me my answer . Hope that helps .

[kengayoka]

2x -5 = 17
2x = 17+5
2x= 22
Thus, x=22/2 = 11. isn't we are supposed to do this way?!!

[ThisMorningReuploads]

Thank you! I will use this in my junior cert tomorrow:)

[Ticktok]

3x+4=19
-4. -4
3x=15
3. 3
X= 5 ❤

[adityarajgaming]

3x+4=19
3×=19-4
3×=15
×=15/3
×=5 ans

[ZiloxPrime]

correct

you isolate x on one side which would give you 2x -5=17 then add 5 to both sides giving you 2x-5=17+5 which ofc equals 22 and then you divide both sides by 2 which is 11

[fcfymrc]

In simple words, 2x - 5=17
2x=17+5(opposite sign due to crossing)
2x=22
x=22/2=11❤

[shubhamzanjal]

X=5 is the right answer according to me

[gaorgoldarts]

QUESTION:
3x + 4 = 19
- 4 - 4
3x = 15

3 3
X = 5

[pirtolilongjoseya]

3x + 4 = 19
3x + 4 - 4 = 19 - 4
3x = 15
Divide 15 by 3
X = 5
