Question

What is the solution to the equation 9-3x = 7?

Answer 1

$\huge{\boxed{x=\frac{2}{3}}}$

Add $3x$ on both sides. $9=7+3x$

Subtract 7 from both sides. $2=3x$

Divide both sides by 3. $\boxed{\frac{2}{3}}=x$

Answer 2

Answer:

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

Step-by-step explanation:

Given

9 - 3x = 7 ( subtract 9 from both sides )

- 3x = - 2 (divide both sides by - 3 )

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