Answer:

  x = 18

Step-by-step explanation:

Add the opposite of the constant (-5), and multiply by the inverse of the coefficient of x (2/3).

  $\dfrac{2}{3}x -5=7\\\\\dfrac{2}{3}x=12 \qquad\text{add 5}\\\\x=\dfrac{3}{2}\cdot 12 \qquad\text{multiply by \dfrac{3}{2} }\\\\ \boxed{x=18}$

Answer 2

Answer:

2/3x -5=7

x=18

Step-by-step explanation:

start by adding each side by 5

after doing so you should have

2/3x =12

multiply each side now my 3/2

the fractions should cancel out and leave x by itself

multiply (12)3/2

gives you 18.

x=18
