Question

Given J = 2hr + 2b, solve for h.

Answer 1

Answer:
`h = (J-2b)/(2r)`

Work Shown:

`J = 2hr + 2b\\\\J - 2b= 2hr\\\\h = (J-2b)/(2r)`

Step-by-step explanation:

In the 2nd step, we isolate the "2hr" by subtracting both sides by 2b. This is do unto the +2b done to the right side initially. We want 2hr all by itself since it contains h.

Then to fully isolate h, we divide both sides by 2r. It might help to think of 2hr as 2r*h so you can pull out the terms easier. The division is done to undo the multiplication.

If writing out the final step using a keyboard, then you would say (J-2b)/(2r). Use parenthesis to indicate which terms are being divided.
