Answer:
-8
Step-by-step explanation:
5(x+12)= 20
5x+60= 20
5x= -40
x= -8
The solution of the system of equation is (-7, -2).
<h2>Given</h2>
The system of the equations;

From equation 1

Substitute the value of y in equation 1

The value of x= 2 is rejected because x = 2 not satisfy the equation.
Substitute 2 for the value of x in equation II
y − x = 5
y – 2 = 5
y = 5 +2
y = 7 (x =2, y =7) … Not included in the options
If x = -7
Substitute the value of x = -7 in the equation

Hence, the solution of the system of equation is (-7, -2).
