I'm reteaching myself algebra using your program and am now easily able to solve these problems without a calculator! I wish I had known about you 4 years ago!

X=17 using the distributive property on both sides you 4x+20=6x-14 adding 14 to both sides and subtracting 4x on both sides creates 34=2x dividing by 2 on both sides x=17

d. 17 in about 10 seconds in my head. Sorry it took so long. Doing too many other things. Nice intro problem!

Got it because I remembered a previous lesson of yours that taught me you can subtract like variables.

First step
Multiply both sides by 1/2.
2(X+5) = 3X -7
Then its distribute
2X + 10 = 3X -7
Combine like terms
17 = X

No need to go into -xs territory
4x +20 = 6x-14
4x+34=6x
34= 2x
X = 2

4(x+5)=2(3x-7)

4x+20=6x-14

-6x+4x=-14-20

-2x =-34

2x=34

x =34/2=17

d) x = 17

4(x + 5) = 2(3x - 7)
4x + 20 = 6x - 14
34 = 2x
34 = 2x
17 = x

X=17 4(x+5) = 2(3x-7) 4(17+5) = 2(3x17 - 7) = 4(22) = 2(51-7) 88 = 2(44) = 88

got it 17 distributite subtract like terms and solve 2X = 34 so X = 17 thanks for the fun

4(x+5) = 2( 3x-7)
4x + 20 = 6x-14
4x-6x = -14-20
-2x = -34
X = 17

Lets just rewrite this to:
2(3x - 7) = 4(x + 5)
6x - 14 = 4x + 20
2x = 34
x = 17

Figuring out X. Let's see if the Youtube Math Dummy can do it! (I mean me!) I've already had my I.Q. improved by maybe a quarter point, .... maybe.

The first objective is to expand everything

Second is to collect like items (apples and oranges.)

Finally, come to a specific equality for x.

4(x+5)=2(3x-7)

Step1
4x+20=6x-14
Step2
4x-6x=-14-20
-2x=-34
Step3
X= -34/-2
=17

VERIFY:
4(x+5)=2(3x-7)
4(17+5)=?2(3(17)-7)
4(22)=?2(51-7)
88=?2(44)
88=❤88✔️

4X + 20 = 6X - 14
