  1. One-Step Equations

  2. A variable is a letter that stands for an unknown number. Inverse (Opposite) Operations The inverse operation of addition is subtraction. The inverse operation of subtraction is addition. The inverse operation of multiplication is division. The inverse operation of division is multiplication.

  3. What does it mean to be balanced? In order to be BALANCED the ______ side and the ________ side must be __________.

  4. Equation Examples * To solve Equations: 1. Get the variable by itself by doing the inverse operation. 2. Think Balance! Whatever you do to the left side you must do to the right! 3. Plug in your answer and CHECK YOUR WORK! X + 3 = 10 m - 17 = -8

  5. You Try! b + 24 = 19 65 = n + 34 y + 89 = 112 41 + k = 7

  6. Check for Understanding h + 35 = 15 a - 4 = -5 r - 3 = 8 450 = a + 325
