Question

This is the last one but how do you find y ? what do I subtract 5 from ?

Answer 1

y = 250

Step 1:

To solve, we plug in 50x for y.

`50x=200+10x`

Then, we subtract the 10x from the right side. Our goal is to get the x by itself first.

`40x=200`

Then, we divide both sides by 40, since we have to get the x by itself.

`(40x)/(40)=x\\\\(200)/(40) =5`

x = 5

Step 2:

Now that we found x, we plug in 5 to the original equation and solve from there.

`y=200+10(5)\\y=200+50\\y=250`

y = 250
