-6 + 4x + (9-2x) = -6 + 4x + 9 - 2x = [ 3 + 2x ]
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
2x + 6x + 4x = 12x
4x-1=2x+1
2x + 4x - x = 5x
2x + 4x + 3 = 6x + 3
4x plus 3 plus 2x is equivalent to expression 6x plus 3.
To simplify the expression 2x + 3y + 4x + 9y, you first combine like terms. Adding the coefficients of x terms gives 2x + 4x = 6x. Similarly, adding the coefficients of y terms gives 3y + 9y = 12y. Therefore, the simplified expression is 6x + 12y.
Ah, what a happy little question! When we have 2x plus 2x, we can combine the like terms to get 4x. It's like adding two beautiful trees together to create a lovely little forest. Just remember, math is like painting, and there are many ways to create something wonderful.
2x + 33 = 4x + 11 -11 -11 2x + 22 = 4x -2x -2x 22 = 4x Divide each side by 4 x = 5.5
4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11
-2x + 6 <= 4x + 18 -2x <= 4x + 12 -12 <= 6x -2 <= x
