Question

How many solutions does the system of equations below have?
y = –10x + 5
y = -10x – 9/7

Answer 1

no solutions

Explanation:

y = –10x + 5

y = -10x – 9/7

They are both equal to y so set them equal to each other

–10x + 5 = -10x – 9/7

Add 10x to each side

–10x + 5 +10x= -10x – 9/7+10x

5 = -9/7

This is never true so there are no solutions
