im a senior in high school and doing credit recovery and need help with math a lot.

First, solve one of the equations for one of the expressions:

-y -5x = -7

+5x +5x

-y = 5x - 7

y = -5x + 7

Then, substitue this for y in the other equation:

2(-5x + 7) -2x = 14

-10x +14 - 2x = 14

-12x +14 = 14

-14 -14

-12x = 0

-12 -12

x = 0

Then, solve the other equation by substituting this value for x.

y = -5x + 7

y = -5(0) +7

y = 0 + 7

y = 7

Now check your work:

-y-5x=-7 Solve where x=0 and y=7

-7 -5(0) = -7

-7-0=-7

-7 = -7

2y-2x=14 Solve where x=0 and y=7

2(7) -2(0) = 14

14-0=14

14=14
