Question

Make x the subject of each
y = 7x + 3b

Answer 1

Answer: (y-3b)/7

Explanation:

Y= 7x+3b

We going to make x the subject of the formula by rearranging.

Y-3b= 7x

To make x stand out, we divide both sides by 7

(Y-3b)÷7=7x÷7

(Y-3b)/7=x

Answer 2

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

Explanation:

Given

y = 7x + 3b ( isolate 7x by subtracting 3b from both sides )

y - 3b = 7x ( divide both sides by 7 )

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