4x + -x = 3x
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
x = -½
x - 2
4x + 5(x - 2) +124x + 5x - 10 + 129x + 2
If: 4x+(-12) = 8 then 4x = 20 and x = 5
The expression (4x + (-x)) simplifies to (4x - x), which equals (3x). Therefore, (4x) plus negative (x) is (3x).
4x =20x=20/4x=5
What is the variable of x plus 10 plus 4x-35?
4x^2 + 3
4x + 17 = x + 2 4x - x = 2 - 17 3x = -15 x = -5
2x + 4x - x = 5x
4(x^2 + x + 3)
X + X + X + X = 4x It is the same as 4 x X = 4x Think numbers . 3 + 3 + 3 + 3 = 12 = 4(3) or 4 x 3 = 12 = 4(3) In mathematics instead of writing a 'string of plusses(+), it is easier to write the number of plusses multiplied to the given number.
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
x2 + 4x = x(x+4)
x2 + 4x = x(x + 4)
ANSWER: -4X2 -8X-4x (x+2)= (-4x * x) + (-4x*2)= -4X2 -8X
