7th Grade Math: Expressions
An expression is a combination of numbers, operators, grouping symbols (such as brackets and parentheses) and/or free variables and bound variables arranged in a meaningful way which can be evaluated. Bound variables are assigned values within the expression (they are for internal use) while free variables can take on values from outside the expression.

This tutorial will show you how to solve linear equations with multiple steps. In order to solve for y, you need to combine like terms. First, reduce by adding constants on the left hand side together, then next, you should combine like terms, y's, and then get y by itself with undoing mutliplication using division.
