If you mean: 2x+y = 18 then y = -2x+18 which is a straight line equation whereas -2 is the slope and 18 is the y intercept
y = 2x + 1 IS a linear equation!
for something to be an equation it has to be equal to something.2x+3=0 would be a linear equation (with x=-1.5) 2x+3+0 is just a series of terms.
Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
The solution to the equation 2x plus 2 is 2(x + 1).
The value of X in the equation 2x plus 36 = 4 is -16.
2x + 4 is an expression, not an equation. There can be no solution set for an expression.
2x plus 3y is not an equation, it is an expression.
-2x plus 3y equals 1
-2x + 8 = 7x - 10 is technically an equation, in and of itself.
It is an equation and the value of x is 1
2x + 5 = 25 2x = 20x = 10
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.
