Question

Which value from the set {3,10,90,108} will make the equation 3x + 3 = 33 true ?

Answer 1

`x = 10` will make the equation true

Explanation:

Given

`\{3,10,90,108\}`

`3x +3= 33`

Required

Which is true for x

We have:

`3x +3= 33`

Collect like terms

`3x= 33 - 3`

`3x= 30`

Solve for x

`x = 30/3`

`x = 10`
