Question

Consider the equation 3a+0.1n=123 if we solve this equation for n which equation would result.

Answer 1

`n = 1230 - 30a`

Explanation:

Given

`3a + 0.1n = 123`

Required

Solve for n

`3a + 0.1n = 123`

Subtract 3a from both sides

`3a - 3a + 0.1n = 123 - 3a`

`0.1n = 123 - 3a`

Divide through by 0.1

`n = (123 - 3a)/(0.1)`

Split the fraction

`n = (123)/(0.1) - (3a)/(0.1)`

`n = 1230 - 30a`
