After the bank cashed a check Maureen wrote for $60, her balance was -$14.The equation b+(-60)=-14 can be used to represent this situation, where b is Maureen’s balance, in dollars, before the check was cashed. Maureen attempted to solve the equation using the steps below.
b+(-60)=-14
-60 -60
b =-74

What error, if any, did Maureen make?
Maureen’s work is correct, and her original balance was -$74.

we are given

[tex]b+(-60)=-14[/tex]

Since, we have to solve for b

[tex]b-60=-14[/tex]

so, we will isolate b ony one side

so, we will add 60 on both sides

[tex]b-60+60=-14+60[/tex]

[tex]b=-14+60[/tex]

[tex]b=46[/tex]

so,

Answer:

Maureen should have added 60 to both sides.

Answer:

Maureen should have added 60 to both sides.

Step-by-step explanation:

In solving this equation, Maureen wants to cancel the -60 in order to get the variable, b, isolated.

To cancel a -60, we would add 60; this is because positive and negative numbers are opposites, and we use opposites to cancel.

Therefore she should have added 60 to each side.
