Question

Rearrange the formula to make x the subject : 5( a - 2x) = 9(x + 1)

Answer 1

x =
`(5a-9)/(19)`

Explanation:

Given

5(a - 2x) = 9(x + 1) ← distribute parenthesis on both sides

5a - 10x = 9x + 9 ( add 10x to both sides )

5a = 19x + 9 ( subtract 9 from both sides )

5a - 9 = 19x ( divide both sides by 19 )

`(5a-9)/(19)` = x
