The expression 10x + 7 + 3x can be simplified by combining like terms. Like terms are terms that have the same variable raised to the same power. In this case, the like terms are 10x and 3x, as they both have the variable x raised to the power of 1. Combining these like terms gives us 13x. Therefore, the simplified expression is 13x + 7.
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
10x+2x-3y-4y=12x-7y
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=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
