12x+2
The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.
x = -5
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
5x+2x-3y+y = (5+2)x+(-3+1)y = 7x - 2y
Separate and simplify the common terms. 5x^2 - X^2 = 4x^2 -7x - 2x = -9x Now put these terms back together 4x^2 - 9x Or if simplified further, you get: x(4x-9)
5x-7x = -2
-12x-2Given: -5x-(7x+2)This is the same as -5x-1(7x+2). Use the distributive property and multiply the -1 through (7x+2).-5x-7x-2Simplify.-12x-2
If you mean: 5x(3x+2)-8x-7x then the expression can be simplified to 15x^2 -5x
5x2+ 7x + 2 = (x + 1)(5x + 2).
If you mean: 7x-2 = 5x+16 then the value of x works out as 9
If you mean: 7x-2 = 5x+16 then the value of x works out as 9
......x^2-5x+2 ------------------------ x-1)x^3-6x^2+7x-2 ......x^3-x^2 -------------------------- ..............-5x^2+7x ..............-5x^2+5x ------------------------- ..........................2x-2 ..........................2x-2 -------------------------- .............................0 The quotient is x^2-5x+2
5x + 17 = 7x - 123 123 + 17 = 7x - 5x 140 = 2x x = 140 ÷ 2 x = 70
To simplify expression 5x + 9 - 7x - 11, you can combine the x terms (5x - 7x) to get -2x, and combine the constant terms (9 - 11) to get -2. Therefore, the simplified expression is -2x - 2.

If you mean: 5x(3x+2)-8x-7x then the expression can be simplified to 15x^2 -5x
7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5
