3x plus 9 equals what?

2x3 - 7 + 5x - x3 + 3x - x3 = 8x - 7

Combine like terms. 6x - 2y +7.

It is: 3x*(x+7)

3x+7=37 -7 -7 3x=30 /3 /3 x=10

13x + 7

3x plus 10x - 7With out knowing what ' x ' actually is.. it will reduce down to.3x + 10 x - 7=13x - 7

7x = 3 x = 3/7

3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3

3x - 2y + 7x + 4y = 3x + 7x - 2y +4y = (3+7)x + (-2+4)y = 10x + 2y

First, subtract 3x from each side of the equation. Then, divide each side of the equation by 7 .

12 - 3x = 24 - 10x so 7x = 12 making x = 12/7 or one and five-sevenths.

10x-7+x+7 = 11x

X>-14

x=7 look at the bottom for the reason: First, when a number and a variable are placed next to each other it means to multiply the 2. (example- what is 3x if x=7 ? Well, 3x7=21 so, 3x=21) so, 5x + 2x + 3x + 10x = 140 20x = 140 40/20 = 7 so, (5x7) + (2x7) + (3x7) + (10x7) = 140 so, 35 + 14 + 21 + 70 = 140
