x = 0 and y = 4
It is a linear equation in x. The equation has the solution x = 0.
If you mean: 2x+5+3x = 25 then the value of x works out as 4
-2x plus 3y equals 1
y = 2x + 1 IS a linear equation!
2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3
2x + 5x + 25 = 17x + 25 = 1Subtract 25 from each side of the equation:7x = -24Divide each side by 7:x = -24/7That's the only answer there is.

It is an equation and the value of x is 1
Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
-2x + 8 = 7x - 10 is technically an equation, in and of itself.
It equals to the equation of a straight line.
It is a quadratic equation.
No.No.No.No.
