One Step Equations Addition and Subtraction

Front

What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions, typically containing one or more variables.

Front

What does it mean to solve an equation?

Back

To solve an equation means to find the value(s) of the variable(s) that make the equation true.

Front

What is the purpose of isolating the variable in an equation?

Back

Isolating the variable allows us to determine its value by getting it alone on one side of the equation.

Front

What is the addition property of equality?

Back

The addition property of equality states that if you add the same number to both sides of an equation, the two sides remain equal.

Front

What is the subtraction property of equality?

Back

The subtraction property of equality states that if you subtract the same number from both sides of an equation, the two sides remain equal.

Front

How do you solve the equation 71 = s + 38?

Back

To solve for s, subtract 38 from both sides: s = 71 - 38, which gives s = 33.

Front

How do you solve the equation s + 38 = -22?

Back

To solve for s, subtract 38 from both sides: s = -22 - 38, which gives s = -60.

Front

How do you solve the equation n + 4 = 12?

Back

To solve for n, subtract 4 from both sides: n = 12 - 4, which gives n = 8.

Front

How do you solve the equation n + 37 = 8?

Back

To solve for n, subtract 37 from both sides: n = 8 - 37, which gives n = -29.

Front

How do you solve the equation n - (-3) = 28?

Back

To solve for n, first simplify: n + 3 = 28. Then subtract 3 from both sides: n = 28 - 3, which gives n = 25.
