Jenny is solving a linear equation
12 + 3x - 5 = 8x + 8 - 5x
Her two final steps are:
7 + 3x = 3x + 8
7 = 8
Select the statement that correctly interprets Jenny's solution.
The solution is the ordered pair (7, 8).
The solution is x = 0.
There are infinitely many solutions since 7 = 8 is a false statement.
There is no solution since 7 = 8 is a false statement.
Melanie earns $6 per hour working for her Dad. Write an equation to find out how many hours she needs to work to earn $54.00.

Solve the following equation.
5x = -25
x=5
x= -5
x = -30
x= -20
Solve the following equation.
x- 7 = -20
x= 27
x= -13
x= 13
x= -27
11 - 3x = 44
52 = -5x - 3
