Question

7x+8y=−46 2y − 6=0 What is the solution (x,y) to the system of equations above?

Answer 1

(-10, 3)

Explanation:

You can do it algebraically (substitution or elimination) or graphically. I will be using substitution to solve this.

Step 1: Rewrite 2nd equation

2y = 6

y = 3

Step 2: Plug in y

7x + 8(3) = -46

7x + 24 = -46

7x = -70

x = -10

Put it in coordinates and we have our final answer!
