Question

It’s multi-step linear equations I have to solve for the x but in this question is asking “expand, and then solve for x” what did it mean by expand 5a - (2a + 15) = 24

Answer 1

Given:

$5a-(2a+15)=24$

To expand and solve for x:

On expanding the given expression, we have,

$5a-2a-15=24$

On solving we get,

$\begin{gathered} 3a-15=24 \\ 3a=24+15 \\ 3a=39 \\ a=13 \end{gathered}$

Therefore, the value of a is 13.
