3x + 5 = 20

Subtract 5 from each side:

3x = 15

Divide each side by 3:

x = 5

3x+5=20 x=5 since 5x3+5=20

2x + 20 = 3x 20 = 3X - 2X 20 = X

2x+10=9+11-3x 2x+10=20-3x 5x+10=20 5x=10 x=2

3x+5=20 3x=15 x=5

-3x + 5 = 20 -3x = 15 x = -5

3x + 8 = 20 - 3x 6x = 12 x = 2

In the equation 3x plus 7 equals 13, x is equal to 2.

8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3

3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4

3x + x + 8 = 20 4x + 8 = 20 4x = 12 x = 3

11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4

4x + 5 = 3x + 8 4x-3x + 5 - 5 = 3x - 3x + 8 -5 x = 3

3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20

-2x+20 = 3x 20 = 3x+2x 20 = 5x 4 = x So x = 4

balance the equation 3x-x=20-6 3x-x=2x 20-6=14 2x=14 x=7

3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4

Ten. That means 3x equals 30, and 30 divided by three is ten.

2x2 + 3x - 20 = (x + 4)(2x - 5).

3x plus -5 equal 7. so x is 4 so 3times 4 is 12-5 will equal 7.

3x plus 9 equals what?

the answer is 33.333333333

3X + 5 = 203X = 15 X = 5

Well lets see: 2y = 6x+8 y=3x+4 does not equal y=3x+6 So they are not the same.

1 + x + 2x = 20 So 1 + 3x = 20 so that 3x = 19 then x = 19/3 or 61/3

3x + 2 = 3x + 6 This is not possible.
