Question

What is the solution to the system of equations?
x+y=5
x-2y=2
(___,___)

Answer 1

Please Help!!

Answer 2

You can rearrange the second equation:

\(\large\color{black}{ \displaystyle x-2y=2 }\)
\(\large\color{black}{ \displaystyle x-2y\color{blue}{+2y}=2\color{blue}{+2y} }\)
\(\large\color{black}{ \displaystyle x=2+2y }\)

And the substitute this for x into your first equation:
\(\large\color{black}{ \displaystyle \color{red}{x}+y=5 }\)
\(\large\color{black}{ \displaystyle \color{red}{\left(2+2y\right)}+y=5 }\)

Answer 3

Can you solve for y from here?
