Question

please help
(x+3)/2 = 5
(y+5)/2 = -11

Answer 1

Oops.. too tired
Well ehh..
\[
\frac{x+3}{2}=5 \quad //⋅2 \\
x+3=10 \quad //−3 \\
x=7
\]
And..
\[
\frac{y+5}{2}=−11 \quad //⋅2 \\
y+5=−22 \quad //−5 \\
y=−27
\]

Answer 3

Those are just the operations made on both sides of the equations, shown in the next line.
Since the whole thing seems to be (unless i'm missing something) quite simple, I thought it would be better to make it clear.
That's how we used to write it in here back then thought it would be more common.
and eh.. it's not .2 it's x2 just with cdot thing
