3(x+5)=2x-3

3X + 15 = 2X - 3

{Subtract 2X from each side to get X on the left}

3X - 2X + 15 = 2X - 2X -3

{Subtract 15 from each side to get value on right}

3X - 2X + 15 - 15 = 2X - 2X - 3 - 15

1X + 0 = 0X - 18

X = -18

3X + 15 = 2X - 3

{Subtract 2X from each side to get X on the left}

3X - 2X + 15 = 2X - 2X -3

{Subtract 15 from each side to get value on right}

3X - 2X + 15 - 15 = 2X - 2X - 3 - 15

1X + 0 = 0X - 18

X = -18

X = X would be a true statement. I think you win in the simplest way possible.

X = X would be a true statement. I think you win in the simplest way possible.

I like smart women. Too many of them it seems play the dumb role. I had to go back in time to remember my algebra lessons.

3(x+5) = 2x-3

(3x)+(15) = (2x) - (3)

(-2x) (-15) = (-2x) (-15)

x=-18

(3x)+(15) = (2x) - (3)

(-2x) (-15) = (-2x) (-15)

x=-18
