10x - 3 - 2x = 4 7x - 3 = 4 7x = 7 x = 1
10x+4y+11xy
3x - 2y + 7x + 4y = 3x + 7x - 2y +4y = (3+7)x + (-2+4)y = 10x + 2y
According to the distributive property, 7x(4y + 4) - 8(4y + 4) = (7x - 8)(4y + 4). Is this question true or false?>
2x plus 5x simplified is 7x.
it means to put together the terms that have the same variable. so if you had the equation: 2x+4y+5x it would simplify to 7x+4y because you would combine to the two x-variables.
7x + 13 = 2x + 3 First, subtract 3 from both sides.7x + 13 - 3 = 2x + 3 - 3Simplify both sides.7x + 10 = 2xNow, subtract 2x from both sides.7x - 2x + 10 = 2x - 2xSimplify again.5x + 10 = 0Finally, subtract 10 from both sides, simplify, and divide both sides by 5.5x + 10 - 10 = 0 - 105x = -10x = -2So the answer is x = -2.
hujkImproved anwser:2x+6 = 7x-42x-7x = -4-6-5x = -10x = 2
(14x^3 - 10x^2) = 2x^2(7x - 5) 63x - 45 = 9(7x - 5) 14x^3 - 10x^2 + 63x - 45 = (2x^2 + 9)(7x - 5)
It can be simplified to: 9y-2x
They add to x+4y simplified
