9x-5x-2x = -4 2x = -4 x = -2
5x-4=8+2x 5x-2x=4+8 3x=12 x=12/3 x=4
2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
5x-4=8+2x 5x-2x=4+8 3x=12 x=12/3 x=4
It is: 10x^2 -4x = 2x(5x-2)
5x-4=8+2x 5x-2x=4+8 3x=12 x=12/3 x=4
x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3
3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8
40
5x+2=2x-10 x=-4
Here is how you solve this problem... 5x*4-3x*5*2x-9= (Combine like-terms) 5x-3x*2x= 2x*2x=(2x)2 (Add the rest of the problem) (2x)2*4*5-9=(2x)2*20-9 (2x)2*11 (2x)2 *11= your answer
5x + 4 - 3x + 5 + 2x - 9 = 4x
