Moira solved a problem on the board. What error did Moira make and how can she correct it?

12x + 10 = 54 - 10x
12x + 10 - 10 = 54 - 10x - 10
12x = 44 - 10x
12x - 10X = 44 - 10x + 10x
2x = 44
X = 22

A- On the left side of the equation, Moira should have subtracted 10x, and on the right side of the equation, Moira should have added 10x.

B- On the left side of the equation, Moira should have added 10x, and on the right side of the equation, Moira should have subtracted 10x.

C- On the left side of the equation, Moira should have added 10x, and on the right side of the equation, Moira should have also added 10x.

D- On the left side of the equation, Moira should have subtracted 10x, and on the right side of the equation, Moira should have also subtracted 10x.

Answer:

C

Step-by-step explanation:

What you do on one side of the equation, you do to the other. She added 10x on the right side and subtracted 10x on the left when she should have added 10x on both sides.
