Question

`- 10a - 9n + 16 - 30 + 3n + 15a + 50 + a =`I'm having trouble comebineing those like terms

Answer 1

Problem:

Solution:

let the expression

-10a -9n + 16-30 + 3n + 15 a + 50 + a =

Putting together similar terms we have

(-10a +15a+a) + (-9n+3n ) + (16-30+50) =

this is equivalent to:

(6a) + (-6n) + (36)

this is equivalent to

6a -6n+36

then, the correct answer is:

6a -6n+36
