Question

`\sf 4x-15=3`

Answer 1

`x=\cfrac{9}{2}\;\; or \;\;4.5`

Explanation:

`4x-15=3`

`4x-15+15=3+15` Add 15

`4x=18`

`\cfrac{4x}{4}=\cfrac{18}{4}` Divide by 4

`x=\cfrac{9}{2}`

Answer 2

`\sf \longmapsto4x-15=3`

`\sf \longmapsto4x = 3 + 15`

`\sf \longmapsto4x = 18`

`\sf \longmapsto{x }= (18)/(4)`

`\sf \longmapsto x = 4.5`
