Question

5x-2y=30 complete the missing value in the solution to the equation

Answer 1

The equation is y=5/2x - 15 or if solving for X is -6

Explanation:

In terms of y=mx+b, we are to make the Y by itself.

Step 1. -2y = -5x +30

Make y become positive!

Step 2. 2y = 5x - 30

Distribut the 2 over to make it 1y.

Step 3. 1y = 5/2x - 15

The equation is y=5/2x - 15

If you are to find X it would be....

-15 divided by 2.5 gets you x= -6

Answer 2

(8,5)

Explanation:

To find the y-value that corresponds to x=8 let's substitute this x-value in the equation.

5x-2y=30

5 x 8-2y=30

40-2y=30

10=2y

5=y

Therefore (8,5) is a solution of the equation.
