Review of Solving Equations
Absolute value equations Isolate the absolute value Set up 2 equations Solve both equations Remember that absolute value equations cannot be set equal to a negative value for example
Multi Step Equations Variables on both sides of the equation Steps: 1st – distribute 2nd – combine like terms 3rd – get variables on 1 side and numbers on the other side by adding or subtracting 4th – multiply or divide 5th – check your answer
-3 + 3b – 4 + 7 = -5b – 2b 3b + 0 = -7b -3b -3b 0 = -10b -10 -10 0 = b
Steps for Solving Equations with Parentheses Step 1: Distribute Step 2: Combine Like Terms Step 3: Move Variable to 1 Side Step 4: Undo + or – Step 5: Undo × or ÷ 3(2x + 5) + 1 = x - 9
To solve a proportion: Follow these easy Steps: Cross multiply Solve the one-step equation for the variable. 3(21) = 4(x) 63 = 4x 63 = 4X 4 4 X = 63/4
To solve radical equations Isolate the radical (if you have two radicals put one on each side of the equation Square both sides Solve for the variable
Let’s TRY one more…
Rational Equations Use the LCM to multiple every term in the equation.
