No. -4 does not equal -2(1).
X=2
-2x plus 3y equals 1
Not sure what you mean; that equation certainly has a solution.
2x + 3 = 72x = 4x = 2
Yes
X=2
-2x plus 3y equals 1
Not sure what you mean; that equation certainly has a solution.
2x + 3 = 72x = 4x = 2
Yes
Yes.
It is a linear equation in x. The equation has the solution x = 0.
An equation, solution x = -10
It does if x=2. That's the solution of your equation.
2x + 4 = 8Subtract 4 from each side of the equation:2x = 4Divide each side by 2:x = 2
x = 0 and y = 4
what is the solution of x-5y=10 and 2x-10y=20
