Question

What is 3 + 17 + x = 10, solve for x?????

Answer 1

First thing you are going to want to do is simplify both sides of the equation, and here is how:
3+17+x=10
Combine Like Terms:
(x)+(3+17)=10
x+20=10
Second is to subtract 20 from both sides, so:
x+20−20=10−20
Answer is:
x=−10

Answer 2

20 + x = 10
20 + -10 = 10
x = -10

hope this helps you
