Question

-x= x – 10

How many solutions does this equation have?

A.Infinitely many solutions

B.No solutions

C.Two solutions

D. One solution

Answer 1

D

Explanation:

Answer: One if any.

-x = x - 10 Add x to both sides

-x+x = x + x - 10 Combine

0 = 2x - 10 Add 10 to both sides

10 = 2x - 10+10 Combine

10 = 2x Divide by 2

10/2=2x/2

x = 5
