x=y+2
x-2y=-1

I'll give Brainliest to the first person
Please explain step by step.

Answer 1

y=3
x=5

Since x=y+2 you can put it in the second equation

(y+2)-2y=-1
If you solve this then

y=3

You can put this in for y in the first equation

x=3+2

So
x=5

Hope this helps!!

Answer 2

We first choose the equation 1 as the formula,then you use equation 2 to be solve.I’ll send a picture for you to understand .Sorry if you see a bracket in y+2 I cancelled for no confusion
