Answer 1

Answer:

x=6

Step-by-step explanation:

Answer 2

Answer:

$\boxed {x = 6}$

Step-by-step explanation:

Solve for the value of $x$ :

$-3 = \frac{2}{3}x - 7$

-Switch sides, and let $\frac{2}{3}x - 7$ be on the left side and $-3$ on right side:

$-3 = \frac{2}{3}x - 7$

$\frac{2}{3}x - 7 = -3$

-Add $7$ to both sides:

$\frac{2}{3}x - 7 + 7 = -3 + 7$

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

-Multiply $\frac{3}{2}$ on both sides, which is the reciprocal of $\frac{2}{3}$ :

$x = 4 \times (\frac{3}{2})$

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

-Divide $12$ by $2$:

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

$\boxed {x = 6}$
