That would be first option since he did use the inverse of subtraction and added 4.5.
Insha's work is incorrectly because -4.5 + (-4.5) will not cancel each other out. It's supposed to be -9, then she should add 9 to cancel -9 out and she would have gotten 3.
Final answer: A
Hope this is clear.
Answer:
x = 11
Step-by-step explanation:
-3x + 4 = -29
step one : subtract 4 from both sides
-3x = -29 - 4
-3x=-33
step two : divide -3 from both sides
-33 ÷ -3 = 11
x = 11
check your work now
-3(11) + 4 = -29
-3 x 11 = -33
-33 + 4 = -29
