You are the correct one. If the person is not able to proof, and if you are rather sure about your answer, it is better to take your own answer instead :)
-9d = 63
<Multiply both sides by (-1)>
=> (-1) × (-9d) = (-1) × 63
=> 9d = -63
=> d = -7
Answer:
x = 5
Step-by-step explanation:
2x - 5 = 5
To solve this, we need to isolate x in all terms. First off, add 5 to both sides:
2x - 5 = 5
2x = 10
Divide 2 by both sides:
2x = 10
x = 5
X - 65 - 4x.
3x - 65.
I assume that you subtract x times four (a number, x, multiplied by 4) FROM the difference of x and 65 (the same number and 65).
Hope this helps!
