Not sure what you mean; that equation certainly has a solution.
2x + 3 = 72x = 4x = 2
It does if x=2. That's the solution of your equation.
An equation, solution x = -10

x = 0 and y = 4
It is a linear equation in x. The equation has the solution x = 0.
It does if x=2. That's the solution of your equation.
An equation, solution x = -10
X=2
the answer is y minus 10 divided by 2.
2x + 4 is an expression, not an equation. There can be no solution set for an expression.
It appears to be a simple linear equation in 'x'. But it has no solution. There is no numerical value for 'x' that can make it a true statement.
The solution is (x, y, z) = (2.5, 1, 2.5).
-2x plus 3y equals 1
