Multiplying 3 and 4 should give you the answer
Answer: 
Step-by-step explanation:
When any number has a negative exponent, all the negative exponent is doing is flipping the sides.
When we plug -3 in for x we get
.
Now just imagine the -3 in fraction form as
. And all you do now is just flip the sides to get 
And now apply the exponent 2 to the 1 and negative 3.
1 to the power of 2 is just 1
-3 to the power of 2 is 9.
So your answer is 
X=11
-5(x+1) = -3(2x-2)
distribute
-5x-5= -6x+6
both +6x
x-5=6
plus 5 on both
x=11
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
