To do this equation, you collect like terms. 7x-4x+x-15 is your original equation, you have 3 terms with "'x'" in them, and they are 7x, -4x, and x. 7x + (-4x) +x simplifies to 4x, because 7-4 = 3 + 1 = 4 (the x is really 1x....). After this, you get 4x-15, which is as simplified as this equation can be.

7x-5+2x=3-4x+12 7x+2x-5=3+12-4x 9x-5=15-4x 9x+4x-5=15-4x+4x 13x-5=15 13x-5+5=15+5 13x=20 13x/13=20/13 x=20/13
-3x plus 4x equals 7x?
No, that's not correct.-3x + 4x = x
What is the factoring for 7x plus 4 x?
Very little factoring. 7X + 4X X(7 + 4) ======
X plus 7x plus 3y - y?
x+7x+3y-y =8x+2y =2(4x+y)
4x2 plus 7x - 15?
(4x - 5)(x + 3) so x = 1.25 or -3
How do you solve 4x plus 9 equals 7x plus 3?
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
7x-5 plus 2x equals 3-4x plus 12?
7x-5+2x=3-4x+12 7x+2x-5=3+12-4x 9x-5=15-4x 9x+4x-5=15-4x+4x 13x-5=15 13x-5+5=15+5 13x=20 13x/13=20/13 x=20/13
What is 4x minus 7 equals 5 plus 7x?
4x - 7 = 5 + 7x x = -4
7x plus 8 equals 4x-10?
Presumably this is an equation in which the value of x is to be found. 7x+8 = 4x-10 7x-4x = -10-8 3x = -18 x = -6
-3x plus 4x equals 7x?
No, that's not correct.-3x + 4x = x
What is the factoring for 7x plus 4 x?
Very little factoring. 7X + 4X X(7 + 4) ======
X plus 7x plus 3y - y?
x+7x+3y-y =8x+2y =2(4x+y)
What is the factor for thetrinomial 4x squared -7x -15?
(4x + 5)(x - 3)
4x2 - 7x - 15?
(4x + 5)(x - 3)
Why is 3x over 4 plus x equal to 7x over 4?
3x/4 + x = 7x/4 because 4x/4 = x 3x/4 + 4x/4 = 7x/4
8 plus 7x equals 20 plus 3x what is x?
8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3
