Question

720 = N + 315 + 240 what is it

Answer 1

Note: N is represented by n instead.

Explanation:

`720 = n + 315 + 240`

Add the numbers

`720 = n + 555`

Move the variable to the left-hand side and change its sign

`- n + 720 = 555`

Collect like terms

`- n = 555 - 720`

Calculate the difference

-N= - 165

N= 165
