Question

Solve the system by substitution.
y, equals, minus, x, minus, 32
y=
−x−32
y, equals, 7, x
y=
7x

Answer 1

Since both equations are equal to y, we can set them equal to each other and solve for x.

-x - 32 = 7x

Adding x to both sides:
-32 = 8x

Dividing both sides by 8:
x = -4

Now we can substitute this value of x into either equation to solve for y. Let's use the second equation:

y = 7x
y = 7(-4)
y = -28

The solution to the system is x = -4 and y = -28.
