GOLDEN RULES OF ALGEBRA here are some reminders to use when solving an equation: keep the problem balanced use inverse operations follow integer rules

constant – a number by itself ex- 7 + x coefficient – a number with variable ex. 15x – 72 CONSTANTS AND COEFFICIENTS

ADDITION EQUATIONS x + 5 = x = use the subtraction property of equality 2. follow integer rules x + (-17) = 74 x = x = 137 x = 123 x + (-23) = 435 x = x = 785 x = 133

SUBTRACTION EQUATIONS x – 13 = x = use the addition property of equality 2. follow integer rules x - (-43) = 32 x = -11x - (-67) = 196 x = 129 x - 98 = 57 x = 456 x = 155 x = 693

MULTIPLICATION EQUATIONS x * (-32) = x = use the division property of equality 2. follow integer rules x * 23 = 273 x = 12x * (- 16) = -480 x = 12x * (- 16) = -480 x = 30 x * 79 = 237 x = 3

DIVISION EQUATIONS x/9 = 36 (9) (9) x = use the multiplication property of equality 2. follow integer rules x/18 = 13 x = 23478/x = 3 x = /x = 3 x = 40

TWO-STEP EQUATIONS 8x – 19 = x = x = x = solve for any addition or subtraction 2. solve for any multiplication or division 3. follow integer rules

q 17x + 24 = 126 x = 20x - (-32) = 112 x = -72x – 3 = 573 x =
