The first one is the 13 in bracket
It’s meant to be 2x multiplied by 4 = 8x
And 2x multiplied by -17 = -34x
The total on the right is not 26x instead, it will be -26x
The next mistake is on the right. So, the right thing is -26x - 8x = -34x
So x = -17 divided by -34
And the answer is 0.5 or 1/2

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
