Answer:
To check if the solution is right you substitute.
Step-by-step explanation:
So in this case you put y = - 6
So you substitute the y as - 6
12(5+2y) = - (6-9y)+4y
12(5+ (2 times - 6)) =(6-(9 times - 6)) + (4 times - 6)
12 times (5+-12) = (6- -6) + - 24
12 times - 7 = 12+-24
-84 = - 12
And that's how to check it basically.
Answer:
Plug in your variables value.
Step-by-step explanation:
For your case, plug in -6 into the y slot
12(5+2y)= -(6-9y) +4y
12(5+2x-6)= -(6-9x-6)+4y see if that works!

Answer:
65ft
Step-by-step explanation:
L=2W-4
PERIMETER=2L+2W
58=2(2W-4)+2W
58=4W-8+2W
58=6W-8
6W=58+8
6W=66
W=66/6
W=11 ANS. FOR THE WIDTH.
L=2*11-4
L=22-4
L=18 ANS. FOR THE LENGTH.
PROOF:
58=2*18=2*11
58=36+22
58=58
