Question

Solve 5ax + 3 ax = 4ax + 12 for x. Assume a is not equal to 0. A. x = 3a B. x = a OC. r- O D r

Answer 1

ANSWER

$x\text{ = }\frac{3}{a}$

EXPLANATION

We want to solve for x in the equation given:

5ax + 3ax = 4ax + 12

To do this, let us collect like terms:

8ax - 4ax = 12

=> 4ax = 12

Divide both sides by 4a:

$\begin{gathered} x\text{ = }\frac{12}{4a} \\ x\text{ = }\frac{3}{a} \end{gathered}$

That is the value of x.
