Question

solve for t: 3y =7tx+b

a. t= (3y-b)/(7x)
b. t= (3y-7x)/b
c. t=(b-7x)/(3y)
d. t= 3y-b-7x

I'm having a hard time solving this math problem. Please explain the steps to solve this! thank you

Answer 1

Hello!

We want to isolate t on one side of the equation. We will use inverse operations to get t alone a seen below. First we subtract b from both sides.

3y-b=7tx

We divide both sides by x

(3y-b)/x=7t

We divide both sides by 7

(3y-b)/x/7=t

Finally we rearrange our equation. We divide by both 7 and x. We could multiply them together and divide as a whole.

t=(3y-b)/7x

The correct answer is A.

I hope this helps!
