Question

Solve the system by substitution.
y = -2
y =
5x + 40

Answer 1

That should be negative 4 as it divided into 40

Answer 2

x = 8.4

y = -2

Explanation:

Step 1: Sub y=-2 into y=5x + 40

-2 = 5x + 40

Step 2: Solve for 'x'

-2 = 5x +40

-42 = 5x

x = 42/5

x = 8.4

Step 3: Solve for 'y'

y is given in the question, y=-2
