Worksheets for linear equations - Homeschool Math Type 3: one-step equations where you first need to simplify an expression on one side (such as 4x = 19 − 7 or 10x − 2x = 16) nonnegative solutions only Type 4: two-step equations (such as 4x − 5 = 19 or (2x) / 6 = 5) Type 5: includes parenthesis (such as 4 (x + 5) = 50) Type 6: variable on both sides (such as 4x + 5 = 9 + 7x)
