What is solving an equation?
Unifying Principle for Equation Solving
By deleting parenthesis and grouping like terms, each side of the equation can be made simpler.
The variable term on one side of the equation can be separated using addition or subtraction.
To find the variable, use multiplication or division.
Consider, the given equation
5(2x - 4) = 10
10x - 20 = 10 Removing parenthesis
10x -20 + 20 = 10 + 20 Adding 20 on both sides
10x = 30 Simplifying
x = 3 Dividing both sides by 10
Hence, the value of x is, x = 3.
