Question

Find x and p: `(2x)/3 - 4 = 10/3`

Sum

Solution

Transposing – 4 to other side, it becomes + 4

∴ `(2x)/3 = 10/3 + 4` ...[Taking L.C.M and adding]

`(2x)/3 = 10/3 + 4/1`

= `(10 + 12)/3`

= `22/3`

`(2x)/3 = 22/3`

Multiplying by 3 on both sides

`(2x)/3 xx 3 = 22/3 xx 3`

⇒ 2x = 22

dividing by 2 on both sides,

We get `(2x)/2 = 22/2`

∴ x = 11
