In algebra it is fully possible for x to equal to zero. After you have 2x, just divide both sides by two, so it would be 2 divided by 0 and than you would have x=0 and that would be your final answer.
2x + 1 = 4x +1
-2x +1 = 1
-2x = 0
divide by -2
x=0
yes I know but will not give answer because you have not say that
5x + 2y =9
X + y= -3
5x+2y=9
2x+2y=-6
__________

X =5
5+y=-3
Y=-8
