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
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.
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.
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.
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.
