Practice your Algebra - 2 variable linear equations - Review - Tutorial and practice questions with answer key. If we have 2 or more linear equations with 2 or more variables, then we have a system of linear equations. Here, we will solve systems with 2 variables, given in 2 linear equations.Below is a list of resources we use in our classroom in our Math classroom, as well as resources to use at home to aid in comprehension and provide additional practice. Please see the above Venn Diagram for a general overview of the similarities and differences between the Math curricula in Grade 7 & 8. For example, if your child is solving the equation 6 + x = 10 for x, he might come up with the answer 16. Have your child 'plug in' the value of the variable by replacing x with 16 in the original problem, to make 6 + 16 = 10.
