2/3 x = 5 multiply both sides by 3
2x = 15 divide both sides by 2
x = 7.5

Or: 2/3X = 5 => X = 5 : 2/3 => X = 5/1 x 3/2 => X = 15/2.

Other way is to cross multiply : x=3*5/2=15/2

The way I was taught is to cross multiply: 2X=15=7-1/2

2/3x=5
2/(3)×=5(3)
X=15/2
:I multiply 3 on both sides

Lol, I knew you had to flip it! Haha, some of that stuff is coming back. I always disliked the Geometry. You know. You got transverse, interior angles, congruence, theorems, all that kind of stuff. I would like to get to a point, to where I am proficient at trig, bur, yeah, gotta pass Geometry, first! Well, I am glad that you know how to do that kind of stuff!

When I substitute the "x"for 7.5 the statement is not true

Bad teaching.... this is a procedure... you need to explain the concept... Why do you need to flip the 2/3??? Maybe you don't you only know that you have to flip the divisor 2/3 because somebody you so... that's terrible teaching... no wonder kids are doing so poor in math these days here in the USA..
