An easy way to check your answers: put your answer (1) in place of your variable (x).
So, does 3x1 + 7 = 2x1?
The left hand side equals 10, but the left hand side equals 2.
1 doesn't make the equation work, so it is not a solution.
To solve the equation (or any linear equation of one variable), get the x on one side and all the other numbers on the other side by doing the same arithmetic (+,-,x,/) to both sides.
3x + 7 = 2x Subtract 2x from each side.
x + 7 = 0 Subtract 7 from each side.
x = -7
So the solution to 3x + 7 = 2x is x = -7.

Why is it no solution when 2x plus 7 equals 1?
Not sure what you mean; that equation certainly has a solution.
Solution of the equation 2x plus 3 equals 7?
2x + 3 = 72x = 4x = 2
What is 2x-2 equals 8 plus 3x?
An equation, solution x = -10
Does x plus 2 equals 2x?
It does if x=2. That's the solution of your equation.
What is the solution to the following equation 7x - 5 equals 2x plus 5?
X=2
