Question

Ok so my problem is -3(3x+15)-(10+x)=35 After doing most of the problem I ended up getting -10x=105. I need to have a whole number as an answer but I can't understand what to do.

Answer 1

i don't know how you got 105. it should be 90.

so,

-10x=90

divide by -10

Answer 2

Hmmmm
-9x-45-10-x=35
-10x=90
x=-9

check that.

Answer 3

Oh thank you both! I for some reason thought 15x3 was 60!
