Answer:
The solution to the system of the equations be:
Explanation:
Given the system of equations

Solving the system of equations using the elimination method
Multiply
by 5:

Multiply
by 2:


adding the equations




now solving -21y = 105 for y

Divide both sides by -21

Simplify

For 10x - 15y = 45 plug in y = -5

Apply the rule -a(-a) = a


Subtract 75 from both sides

Simplify

Divide both sides by 10

Simplify

Therefore, the solution to the system of the equations be:
