Question

Y=-x+1
Y= 2/3x-4
How many solutions does it have?

Answer 1

x = -5

Y = -22/3

Explanation:

Y= 2/3x - 4 Y = -x + 1

We put -x + 1 in for y to solve for x

-x + 1 = 2/3x - 4

-5/3x + 1 = -4

-5/3x = -5

x = -5

Now put -5 in for x and solve for y

Y= 2/3(-5) - 4

Y = -10/3 - 4

Y = -22/3

So, there are only one solution x = -5 and y = -22/3
