Simplifying
5.5 + -1x = -4.5 + -1x
Add 'x' to each side of the equation.
5.5 + -1x + x = -4.5 + -1x + x
Combine like terms:
-1x + x = 0
5.5 + 0 = -4.5 + -1x + x
5.5 = -4.5 + -1x + x
Combine like terms:
-1x + x = 0
5.5 = -4.5 + 0
5.5 = -4.5
Solving:
5.5 = -4.5
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
Hope this helps!
