If you mean: x+4x--9 = x+1 then 4x = -8 and x = -2
If: 4x = x+15 Then: x = 5
All we have to do is subtract the coefficients of the x terms. The solution is -4x.
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
x=1/4
x>5
All we have to do is subtract the coefficients of the x terms. The solution is -4x.
5x - 9 = 4x 5x - 4x - 9 = 4x - 4x x - 9 = 0 x - 9 + 9 = 0 + 9 x = 9
-4x + 2 = 6 -4x = 6 - 2 -4x = 4 x = 4 / -4 x = -1
The solution of 4x plus 3y -9 and x -3 is; 5x+3y-3.
There is no solution yet, for x is an unknown. Once x is known, one can plug in the numbers. 4x-2=4x-2 because they are the exact same on both sides of the equal sign.
4x+9=25 4x=16 x=4
