Answer :
C because if you want his age six years ago, you need to take his present age (A) and subtract 6
Answer:
x = -7
Step-by-step explanation:
-6x + 3 = 45
First, we need to get rid of the 3 by subtracting it by 3. We need to do the same to the number on the other side.
-6x + 3 = 45
-3 - 3
-<em>6x = 42</em>
Then, to iolate the x, we need to divide -6 by itself to cancel the number out and get x alone. We also need to divide 42 by -6 as well.

42 divided by -6 is -7.

I hope this helps!
3/4z - 1/4z + 3 = 2/4z + 5
3/4z - 1/4z - 2/4z = 5 - 3
2/4z - 2/4z = 2
0 ≠ 2

When u keep dividing and dont get it go up by each number and keep divind by every number until u get it which would be
