Question

what is the missing value for x-5y=-15

Answer 1

Answer:

y= 1/5 (fraction)

x=−3

Step-by-step explanation:

Let's solve for x.

x−5y=15

Step 1: Add 5y to both sides.

x−5y+5y=15+5y

x=5y+15

Let's solve for y.

x−5y=15

Step 1: Add -x to both sides.

x−5y+−x=15+−x

−5y=−x+15

Step 2: Divide both sides by -5.

−5y

−5

=

−x+15

−5
