8-4k = 40
(4k-8) - 8 = 40-8
4k = 32
4k/4 = 32/4
k =8
x = 8

5x-3=37 (Original Equation) 5x=40(Add 3 to the right side) x=8(Divide 40 by 5)
3n-8 = 32-n add n to both sides 4n-8 = 32 add 8 to both sides 4n = 40 divide both sides by 4 n = 10
x = 40

x=100
2.75y = 110 y = 40
The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.
Is v a variable? This isn't an equation. For there to be a value for v, there needs to be an equals sign somewhere.
If the equation is -20x-5y=40 then the answer is -5y=20x+40 which equals y=-4x-8 If the equation is -20x+5y=40 then the answer is 5y=20x+40 which equals y=4x+8
