Grade 8 - Patterns and Relations

Standard 8.PR.2 - Practice solving two step linear equations by combining like terms.

Included Skills:

Model and solve problems concretely, pictorially and symbolically, using linear equations of the form:
• ax = b where a, b and c are integers.
• x/a = b, a ≠ 0 where a, b and c are integers.
• ax + b = c where a, b and c are integers.
• x/a + b = c, a ≠ 0 where a, b and c are integers.
• a(x + b) = c where a, b and c are integers.
• Model a given problem with a linear equation; and solve the equation, using concrete models, e.g., counters, integer tiles.
• Verify the solution to a given linear equation, using a variety of methods, including concrete materials, diagrams and substitution.
• Draw a visual representation of the steps used to solve a given linear equation, and record each step symbolically.
• Solve a given linear equation symbolically.
• Identify and correct an error in a given incorrect solution of a linear equation.
• Apply the distributive property to solve a given linear equation; e.g., 2(x + 3) = 5 is equivalent to 2x + 6 = 5.
• Solve a given problem, using a linear equation, and record the process.
