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
If: 3x+20 = 2x-10 Then: x = -30
x = 2
2x + 3x = 5x
x=4
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
Do you mean "what is the value of x when 3x - 2x = 15?" in that case, the value of x is 15
5X + 6 = 2X + 15 -2X -2X 3X + 6 = 15 -6 -6 3X = 15 ---- ----- 3 3 x = 5 im so smart.
If 3x + 3 = 2x + 6 then 3x - 2x = 6 - 3 x = 3
If: 3x+20 = 2x-10 Then: x = -30
2x + 5
3x + 2x - 8x + 2x = -x
It is 2x - 8
x+5 = 3x+15 x-3x = 15-5 -2x = 10 x = -5
x = 2
2x + 3x = 5x.
2x + 3x = 5x
