Unformatted text preview: have a variable. If the solution is correct, both sides of the equation will be equal. In the step list above some steps might not be necessary. EXAMPLE: 0.5(5 + 2) = 24/2 (1) Step 1: Multiply both terms of the parenthesis with 0.5 to eliminate the parenthesis. Equation becomes: 2.5 + 1 = 24/2 Step 2: Multiply both sides by 2 to eliminate the fraction of the Right Hand Side. Equation becomes: 5 + 2 = 12 Step 3: There are no like terms in each side so we go to step 4. Step 4: We subtract from both sides 2 in order to eliminate the 2 in the Left Hand Side (LHS). Equation becomes: 5 = 10 Step 5: We divide both sides by 5 to cancel the 5 from the LHS and therefore = 2 Now, try to put 2 instead of in equation (1) and check if the two sides are equal....
