What's the answer for 3/4 (x+3)=9

Vitek1552 [10]

We want to solve the equation :

$\displaystyle{ \frac{3}{4}(x+3)=9$

first, multiply both sides by 4:

$\displaystyle{ \cancel{4} \cdot \frac{3}{ \cancel 4 }(x+3)=4\cdot 9$

$\displaystyle{ 3(x+3)=36$

divide both sides by 3:

$x+3=12$

add -3 to both sides:

$x=9$

Answer: x=9
