Question

What is the solution of the system of equations?
y=x-10
y= 2x + 5
A. (15,25) B. (15,-25) C.(-15, -25) D.(-15, 25)

Answer 1

Answer:

C

Step-by-step explanation:

y=x-10

y= 2x + 5

x - 10 = 2x + 5  Use substitution

-10 = x + 5  Subtract x from both sides

-15 = x  Subtract 5 from both sides

y = -15 - 10  Plug your answer into the equation to find y

y = -25
