Algebra Can be summed up in 3 words: Variables Expressions Equations

Solving equations Find the variable Figure out what you are doing to the variable (adding to it, subtracting from it, multiplying it, or dividing it) Do exactly the opposite using one of the Rules of Equality (Addition, subtraction, multiplication, or division)

H + 6 = 47 23 + G = 12

Addition with a variable Z + 23.8 = 34.2 R + 5/6 = 4 ½ 34 + P = 22 In your folder – use as notes! These are called one-step equations……..
