Question

What point is the solution to the system of equation y= - 1/2 and y=2x-5

Answer 1

x = 2 1/4 y = -1/2

Explanation:

y= - 1/2

y=2x-5

Substitute y = -1/2 into the second equation

-1/2=2x-5

Add 5 to each side

5-1/2 = 2x-5+5

4 1/2 = 2x

Multiply each side by 1/2 to isolate x

9/2 *1/2 = 2x * 1/2

9/4 = x

Change to a mixed number

2 1/4 =x
