3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
3x+12x = 15 15x = 15 x = 1
4x+7-3x = 15 4x-3x = 15-7 x = 8
Presumably, this is an equation in finding the value of x 3x+5/4 = -2x+15 3x+1.25 = -2x+15 3x+2x = 15-1.25 5x = 13.75 x = 2.75
3x + 15 = 603x = 60 - 153x = 45x = 45/3Therefore, x = 15.
3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
x+5 = 3x+15 x-3x = 15-5 -2x = 10 x = -5
no
If 15 + 3x = 42, then x = 9
3x+12x = 15 15x = 15 x = 1
4x+7-3x = 15 4x-3x = 15-7 x = 8
3x^2 -14x +15 = (3x-5)(x-3)
6x + 4 = 3x + 19 3x + 4 = 19 3x = 15 x = 5 Check it. 30 + 4 = 15 + 19 It checks.
Presumably, this is an equation in finding the value of x 3x+5/4 = -2x+15 3x+1.25 = -2x+15 3x+2x = 15-1.25 5x = 13.75 x = 2.75
3x + 15 = 603x = 60 - 153x = 45x = 45/3Therefore, x = 15.
negative 15
i don't know, why are you asking me? :)
