5X + 6 = 2X + 15 -2X -2X 3X + 6 = 15 -6 -6 3X = 15 ---- ----- 3 3 x = 5 im so smart.
What is 3x plus 2 equals 3x plus 6?
3x + 2 = 3x + 6 This is not possible.
4x plus 6 equals 21 plus 3x?
x = 15 as 4*15+6 = 66 3*15+21 = 66 or an easier way to do it 4x - 3x = 1x 21 - 6 = 15 1x = 15
What is answer 3x-6 equals 15?
3x-6=21-6=15
What is 9x plus 6 equals 6x plus 15?
