Question

Y = -3x + 2

Y = 2x - 4

How can you determine the exact solution to this system of equations?

Answer 1

x = 6/5 y=-8/5

Explanation:

Set the two equations equal to each other

Y = -3x + 2

Y = 2x - 4

-3x+2 = 2x-4

Add 3x to each side

-3x+3x + 2 = 2x+3x - 4

2 = 5x-4

Add 4 to each side

6 = 5x

Divide by 5

6/5 =x

The find y

y = 2x-4

= 2(6/5) -4

=12/5 - 20/5

-8/5
