Question

Solve using substitution please

y=-3x - 10
y = 6x + 8

Answer 1

x= -2

Explanation:

Because both functions are equal to y wr can set the equations equal to each other and solve for x

-3x-10=6x+8

-3x=6x+18.

-9x=18

x=-2.

Answer 2

6x+8=-3x-10
9x=-18
x=-2
-3(-2)-10=-4
So x=-2 and y=-4
