Question

Rearrange the following formula to make y the subject of the equation.

a= 3y-4
______
6

Answer 1

I'll show you how to solve a similar problem (just with different numbers)

\[\Large a = \frac{8y - 5}{2}\]

\[\Large {\color{red}{2*}}a = {\color{red}{2*}}\frac{8y - 5}{2} \ \text{multiply both sides by 2}\]

\[\Large 2a = 8y - 5\]

\[\Large 2a{\color{red}{+5}} = 8y - 5{\color{red}{+5}} \ \text{add 5 to both sides}\]

\[\Large 2a+5 = 8y\]

\[\Large \frac{2a+5}{{\color{red}{8}}} = \frac{8y}{{\color{red}{8}}} \ \text{divide both sides by 8}\]

\[\Large \frac{2a+5}{8} = y\]

\[\Large y = \frac{2a+5}{8}\]

again, this is not the answer as it's just a similar example

Answer 2

so would the answer be

y = 2a+4
