x+3(x+1)=2x
x + 3x + 3 = 2x
2x + 3 = 0
2x = -3 or x = -1.5
X equals 2 :)
... which is 2x + 2 = x so x = -2
It equals to the equation of a straight line.
It equals 8x+12

It equals x+5y simplified
it equals 13X.
3.5
It doesn't; it equals 2x. Only if x = 0 does 2x = x.
X + ( 2Y - 2X - Y ) is equal to Y - X
2x must equal 12 so x is 6.
