Step-by-step explanation:
If you lost "y" in the first equation.

If first equation is correct.

Answer:
m = -21
Step-by-step explanation:
9+m/3=2
1. Subtract 9 from both sides
9 - 9 + m/3 = 2 - 9
m/3 = -7
2. Multiply both sides by 3
3 (m/3) = -7 (3)
m = -21
Answer: (x=+17)
Step-by-step explanation:
x+35=3x+1
We move all terms to the left:
x+35-(3x+1)=0
We get rid of parentheses
x-3x-1+35=0
We add all the numbers together, and all the variables
-2x+34=0
We move all terms containing x to the left, all other terms to the right
-2x=-34
x=-34/-2
x=+17
4m = 12x + 40
8x + 8x + 12x + 40 + 4m = 360
28x + 40 + 12x + 40 = 360
x = 7
m = 12(7) + 40 = 124
