x = 18 is the solution to equation

Solution:

Given equation is:

2 over 3 x = 12

Here, "over" means division

Therefore,

(2 divided by 3 ) x = 12

Which means,

$\frac{2}{3} x= 12\\$

Multiply both sides by 3

$\frac{2}{3}x \times 3 = 12 \times 3\\\\2x = 36$

Divide both sides by 2

$\frac{2x}{2} = \frac{36}{2}\\\\x = 18$

Thus, x = 18 is the solution to equation
