y = 2x + 2
Variables are just letters to solve for the unknowns. ex of a variable: 4x-6 = 16 x is a variable in this case, so we solve for it 4x = 22 x = 11/2
To solve a two-step equation with a fraction and a variable, first isolate the term with the variable by eliminating any constant on the same side. You can do this by adding or subtracting the constant from both sides. Next, if the variable is multiplied by a fraction, multiply both sides of the equation by the reciprocal of that fraction to solve for the variable. Finally, simplify to find the value of the variable.

You may want to be a little more specific about what your question is asking....... you can solve a variable in an equation or expression. For example: 1+2=y just remember, you arnt necessarily "solving" a variable, but I guess you could say that considering a variable can change continuously. Be sure to consider that if you do "solve" a variable you end up with a constant ( a never-changing number) therefore, it is no longer a variable, but just an answer. Hope that helped! :-)

There is no equation (nor inequality) in the question. There is also no unknown variable. So there is nothing to solve.
To solve a system of two-variable equations, you can use one of three main methods: substitution, elimination, or graphing. In the substitution method, you solve one equation for one variable and substitute that expression into the other equation. In the elimination method, you add or subtract the equations to eliminate one variable, allowing you to solve for the other. Graphing involves plotting both equations on a coordinate plane and identifying the point where they intersect, which represents the solution.

Your equation has two variables in it ... 'a' and 'x'. So the solution is a four-step process: 1). Get another independent equation that relates the same two variables. 2). Solve one of the equations for one of the variables. 3). Substitute that into the other equation, yielding an equation in a single variable. Solve that one for the single variable. 4). Substitute that value back into the first equation, and solve it for the second variable.
