7 x - 4 x + 2 x+5 = 2 x + 14 --- (1) Shift those terms containing "x" on left side and constants on other side 7 x - 4 x + 2 x - 2 x = 14 - 5 We will get 3 x = 9 Divide both sides by "3" we get; x = 3
Right, 3x-4x+9x-x1. 3x - x = 2x2. 9x-4x = 5x- 2x +5x = 7x
-4x
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
2x2-4x-3x+6 2x2-7x+6 (2x+3)(x+2)
3x + (-2 + 4x) = -2 + 7x
3x + 4x = 7x
-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3
5x+3x-6x+4x+2x-x+10 This expression can be simplified to: 7x+10 (7 being the coefficient of x)
No, that's not correct.-3x + 4x = x
4x-2y+3x+2y When simplified: 7x
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
