What is the value of x in the equation -2/3 x + 9 = 4/3 x - 3?

anygoal [31]

Answer:

x = 6

Step-by-step explanation:

We want to solve:

$\frac{-2}{3} x+9=\frac{4}{3} x-3$

First, isolate the variable by moving all the terms with x to one side and all the constants to the other side:

$\frac{4}{3}x +\frac{2}{3} x=9+3$

Combining the fraction on the left, we get:

$\frac{6}{3} x=12$

6/3 = 2, so:

2x = 12

Dividing both sides by 2 yields:

x = 6
