Answer:

The first term should be positive

She did not distribute the -4 properly

She added \frac{2}{7} to negative -4 instead of multiplying

Step-by-step explanation:

In order to tell where she is wrong we should solve the question our selves. we are going to get the following......

-4(-3x + \frac{2}{7})= -4(-3x) +  (-4)(\frac{2}{7} )= 12x - \frac{8}{7}

So now we see that the three things she did wrong are.

The first term should be positive

She did not distribute the -4 properly

She added \frac{2}{7} to negative -4 instead of multiplying

Hope this helps :)
