Question

Rearrange w=3(2a+b)-4 to make a the subject

Answer 1

a=
`(-1)/(2)`b+
`(2)/(3)`+
`(1)/(6)`w

Explanation:

Original equation: w=3(2a+b)-4

1. Distribute the 3 to the numbers inside parenthesis to get:

w=6a+3b-4

2. Subtract 6a from both sides to get:

-6a+w=3b-4

3. Subtract w from both sides to get:

-6a=3b-4-w

4. Divide both sides by -6 and simplify to get:

a=
`(-1)/(2)`b+
`(2)/(3)`+
`(1)/(6)`w
