Hope this helps!!!
Step-by-step explanation:
An equation is a mathematical statement that two expressions are equal. The solution of an equation
is the value that when substituted for the variable makes the equation a true statement.
Our goal in solving an equation is to isolate the variable on one side of the equation and a number on
the other side so the equation reads:
Variable = Number
To achieve our goal, we use two principles of equality, the addition principle and the multiplication
principle.
• Use the addition principle to move terms from one side of the equation to the other side. To
move a term, add it's opposite to both sides of the equation.
• Use the multiplication principle to solve for the variable. If the variable is multiplied by a
number, divide both sides of the equation by that number. If the variable is divided by a
number, multiply both sides of the equation by that number.
To solve equations, use the procedure outlined below.
Steps for Solving Equations
Step 1: Clear fractions and decimals by multiplying each term of the equation by the LCD (least
common denominator).
Step 2: Remove the parentheses by distributing.
Step 3: Combine any like terms found on the same side.
Step 4: Use the addition principle to move the variable term to one side of the equation and the
number to the other side.
Step 5: Multiply or divide to solve for the variable.
Step 6: Check the result in the original equation.
