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
