y=24. if you use the property that states: if a=b, and b=c, then a=c. so basically if you just reword your problem it will sound just like the property. if y=6x and 6x=24, then y=24.
6x - 12 = 3x + 12 Add twelve to both sides.6x - 12 + 12 = 3x + 12 + 12Simplify.6x = 3x + 24Subtract 3x from both sides.6x - 3x = 3x + 24 - 3xSimplify.3x = 24Divide both sides by 3.x = 8The answer is x = 8.
8x + 6 = 2x + 24 To solve, collect like terms on each side; collect the x's on the left, the numbers on the right: 8X + 6 = 2x + 24 8x - 2x = 24 - 6 6x = 18 6x / 6 = 18 / 6 x = 3
d/dx (ln(6x)) = (d/dx (6x))/(6x) = 6/6x = 1/x
6x - 3y
