3x+8 = 2x+5 Subtract 2x from both sides: x+8 = 5 Subtract 8 from both sides: x = -3
3x-2=x+8 (+2) 3x=x+10 (-x) 2x=10 (/2) x=5
2x-5=3x+6 -5-6=3x-2x -11=x x=-11
2x+12-3x = 5 2x-3x = 5-12 -x = -7 x = 7
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
3x+5 = 2x+13 3x-2x = 13-5 x = 8
3x+8 = 2x+5 Subtract 2x from both sides: x+8 = 5 Subtract 8 from both sides: x = -3
3x-2=x+8 (+2) 3x=x+10 (-x) 2x=10 (/2) x=5
2x-5=3x+6 -5-6=3x-2x -11=x x=-11
2x+12-3x = 5 2x-3x = 5-12 -x = -7 x = 7
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
It helps to get all your "x" terms on one side of the equation and all your constants on the other. So it would be easiest in this case to subtract 2x from both sides, to remove the x from the right side, and add 5 to both sides, to remove the constant from the left. So you get: 3x - 5 - 2x + 5 = 3 + 2x - 2x + 5 (3x - 2x) + (-5 + 5) = (2x - 2x) + (3 + 5) x + 0 = 0 + 8 x = 8
Are you asking how to find the value of x? If so: 3x-3 = x+5 3x-x = 5+3 2x = 8 x = 4
-3x+2 = 2x-8 8+2 = 2x+3x 10 = 5x x = 2
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
Simplify by combining the like terms. x + 5 - 2x + 3 = 8 - x 7 - 3x - 1 = 6 - 3x 8 - x = 6 - 3x 8 = 6 - 2x 2 = -2x x = -1 Check by plugging -1 into the original equation. -1 + 5 - (-2) + 3 = 7 - (-3) - 1 9 = 9 It checks.
According to my calculations, yes. 2x+8=3x+11 -8 2x=3x+3 -2x 0=x+3 -3 -3=x
