Solve the system of equations using the substitution method. {y=−3x+7 {x=−2y−16 enter your answers in the boxes. x= y=

x = 6 & y = -11

Step-by-step explanation:

You take the equation (y=-3x+7) and put it in the x equation...

x =-2(-3x+7)-16 -- Then continue with the math

x = 6x-14-16

x=6x-30

-5x=-30

x = 6

Then you continue to subsitute the x into the y equation

y= -3(6)+7

y= -18+7

y= -11
