Question

Substitution y=× +5 2x-y=-2

Answer 1

We know what y equals already. 

y = x + 5

2x - x + 5 = -2
x + 5 = -2
    -5      -5

x = -7

y = -7 + 5
y = -2

Now we have our values

Answer: (-7,-2) 
or
x = -7
y = -2

Answer 2

So, we substitute the y in the second equation to solve for x-value.

2x-(x+5) = -2
2x-x-5 = -2
x-5 = -2
  +5   +5
x = 3

As we got the x-value, we now have to find the value of y.

y = x+5
y = 3+5
y = 8

So, the answer is (3,8)
