# Math Help - Algebra

1. ## Algebra

could someone help me to understand,

algebra question below and I don't know how to solve for x, with x = -11

1/2(5-x) = -3

I'm not sure what to do with the half, do I subract it from -3 or devide? not happy, been doing really well learning from scratch and I've hit this wall.

Leg up?

2. Hi!

Short explanation:

$\frac{1}{2}$ is multplying so it should divide $-3$

Reasoning

Your $\frac{1}{2}$ is multiplying $(5-x)$, so what you should do it's multiplying by $2$ both members (It won't change anything in our case, think $1=1$ it's the same as $1\cdot2=1\cdot2$ . Then you have $2\cdot\frac{1}{2}\cdot(5-x)=2\cdot(-3)$.
