The system of equations y =-2x + 1 and y = x + 5 is shown on the graph below. Which statement is true about the solution to the system of equations?
O The x-value is between-1 and-2, and the y-value is betwe

answer:

c. the third graph

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
