Solve the system of equations using the substitution method.

-5x - 3y = 16

y = x

-5x - 3x = 16

-8x = 16

x = - 2

y = x

(-2, - 2)

Step-by-step explanation:

Make use of the 2nd equation to eliminate x or y in the 1st equation:

-5x - 3 (x) = 16

Then - 8x = 16, and x = - 2. Since we are told that y = x, y = - 2.

The solution is (-2, - 2).
