It equals 7 since 2x = 7+x where 2 has 2x but 7 is one x because there is only one x . So it is 7.
X equals 2 :)
It equals to the equation of a straight line.
x = 7
3
It equals 8x+12
4
2x + 3y = 1 y = 1/3 - 2x/3
it equals 13X.
X=1.42857142857143
It equals x+5y simplified
3.5
X + ( 2Y - 2X - Y ) is equal to Y - X
