7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
2x plus 5x simplified is 7x.
7x + 5y 7(3) + 5(2) 21 + 10 = 31
2x2 + 7x - 15 = (2x - 3)(x + 5)
Like terms are: 5x -7x +2x and 3 -5
(7x-3y) + (2x+5y) = 9x+2y
It can be simplified to: 9y-2x
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
2x+5y-7x+2xy combine like terms 5y-5x+2xy that's simplified because there are only 3 terms (x, y, and xy) you cannot combine x and y unless it's being multiplied
They add to x+4y simplified
It is: 7x+10y
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.
It works out that the solutions are: x = 3 and y = 2
2x+4+7x-4 is the same as 9x
7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
It works out that: x = 3 and y = 2
7X + 4 - 2X + 9 = 0 Move all constants to the opposite side- 7X - 2X = -9 - 4 Simple addition and subtraction- 5X = -13 Get X by itself by division- X = -13/5 There you go :)
