2x+3=9x 3=9x-2x 3=7x x=3/7
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
2x 5 -7 = 3
y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7
2x + 3 = x - 4 2x + 7 = x x + 7 = 0 x = -7 2(-7) + 3 = -11 (-7) - 4 + -11
2x+3 = 7 2x = 7-3 2x = 4 x = 2
2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9
2x + 7 = 1 Therefore, 2x = -6 x = -6/2 x = -3
2x + 3 = 9x Subtract 2x from both sides: 3 = 7x Divide both sides by 7: 3/7 = x
2x+3 = -11 2x = -11-3 2x = -14 x = -7
5x+7 = 2x-3 5x-2x = -3-7 3x = -10 x = -10/3
x-2=7 x=7+2x=9dips**t
3x+4 = 2x-3 3x-2x = -3-4 x = -7
2x+3=9x 3=9x-2x 3=7x x=3/7
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
2x/7 = 11 Multiply both sides by 7: 2x = 77 Divide both sides by 2: x = 77/2 = 38.5
