Question

Rearrange x = 3g + 2 to make g the subject.

Answer 1

g = ( x - 2 ) / 3

Explanation:

x = 3g + 2

subtract 2 from each side

x - 2 = 3g + 2 - 2

simplify

x - 2 = 3g

Divide each side by 3

(x - 2)/3 = 3g/3

Simplify

( x - 2 ) / 3 = g

Flip equation

g = ( x - 2 ) / 3

And we are done!
