Answer:
The solution to the system of equations be:
Step-by-step explanation:
Given the system of equations
x + y = 12
-x + 2y = 15
Let us solve the system of equations by elimination

adding the equations




solve 3y = 27 for y

divide both sides by 3

Simplify

For x+y=12 plug in y = 9

Subtract 9 from both sides

Simplify

Therefore, the solution to the system of equations be:
Step-by-step explanation:
6(p+3)-6(p+5)=6p+18-6p-30=-12
