Answer:
(-10, 3)
Step-by-step 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 <em>y</em>
7x + 8(3) = -46
7x + 24 = -46
7x = -70
x = -10
Put it in coordinates and we have our final answer!

Answer:
5.6x-16.9=-0.1
28x/5-16.9=-0.1
28x/5-16.9=-0.1
28x/5-16.9+16.9=-0.1+16.9
28x/5=16.8
