Question

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

Answer 1

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
