Answer:

x=-73 and y=51

Step-by-step explanation:

1. Rewrite Equation

y=51 , -2x-3y=-7

2. Solve y=51 for y

y=51

3. Substitute 51 for y in -2x-3y=-7

-2x-3y=-7

-2x+(-3)(51)=-7

-2x-153=-7 <simplify both sides of the equation>

-2x-153+153=-7+153 <add 153 to both sides>

-2x=146

-2x/-2 = 146/-2 <divide both sides by -2>

x=-72
