Solving Addition and Subtraction Equations
Inverse operation is an operation that “undoes” another operation. Addition and subtraction are inverse operation. Equivalent equations are two equations that have the same solution(s)
Subtraction Property of Equality Subtracting the same number from each side of an equation produces an equivalent equation. Algebra: x + a = b x + a – a = b - a
Addition Property of Equality Adding the same number to each side of an equation produces an equivalent equation. Algebra: x - a = b x – a + a = b + a
Modeling Solve x − 5 = −1.
2 = 1.3 + a + 4
Real-life Application A company has a profit of $120.50 today. This profit is $145.25 less than the profit P yesterday. Write an equation that can be used to find P. Then, solve for P.
