Question

Find the solution to the system of equations.

You can use the interactive graph below to find the solution.
y = -7x + 3
y = -x - 3
2 =
y =

Answer 1

x = 1

y = -4

Explanation:

y = -x - 3

y + 3 = -x

x = - y - 3

y = -7(-y - 3) + 3

y = 7y + 21 + 3

y = 7y + 24

-6y = 24

y = -4

-4 = -x - 3

-1 = -x

x = 1
