Question

What is the answer for this question, can you please solve step by step?

Answer 1

x = -3, y = -5

Explanation:

Given equations:

-6x - y = 23 ----------------(1)

y = 4x + 7 -------------------(2)

Put Eq. (2) in (1)

-6x - (4x + 7) = 23

-6x - 4x - 7 = 23

-10x - 7 = 23

• Add 7 to both sides

-10x = 23 + 7

-10x = 30

• Divide both sides by -10

x = -3

Put x = -3 in Eq. (2)

y = 4(-3) + 7

y = -12 + 7

y = -5
