Find the mistakes in the equations

Second line on the right side of the equation it should be 2x(-13)

so then 8x - 24 + 7 = -26x
8x - 17 = -26x
then in hers she added the 8 to 26 when she should have subtracted it
it should be -17 = -34x
so 17 = 34x
1/2 = x

A)26•2=52there are 2 sides with the same length116-52=64the other 2 side have to be half of 64 each64/2=32the width is 32b)make two sentences about these steps because your teacher knows how you write and explain things.
