Question

What is the solution to the equation x + 8.5 = 64.5? 7.6 48 56 73

Answer 1

Simplifying
x + 8.5 = 64.5
 
Reorder the terms:
8.5 + x = 64.5
 
Solving
8.5 + x = 64.5

Solving for variable 'x'.
 
Move all terms containing x to the left, all other terms to the right.

Add '-8.5' to each side of the equation. 
8.5 + -8.5 + x = 64.5 + -8.5
 
Combine like terms:
8.5 + -8.5 = 0.0
 0.0 + x = 64.5 + -8.5
 x = 64.5 + -8.5
 
Combine like terms: 64.5 + -8.5 = 56
x = 56
 
Simplifying x = 56

Answer 2

The solution to x + 8.5 = 64.5 is 56.

    x + 8.5 = 64.5
       - 8.5   - 8.5
---------------------------
    x = 56
