Addition and Subtraction One-Step Equations

Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single operation, such as addition, subtraction, multiplication, or division.

Front

How do you solve the equation q + 10 = 22?

Back

To solve for q, subtract 10 from both sides: q = 22 - 10, so q = 12.

Front

What is the first step to solve the equation n + 6 = 16?

Back

Subtract 6 from both sides to isolate n: n = 16 - 6, so n = 10.

Front

How do you isolate the variable c in the equation 8 = c - 4?

Back

Add 4 to both sides to isolate c: c = 8 + 4, so c = 12.

Front

What is a complementary angle?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

How do you solve the equation 54 = s + 34?

Back

To solve for s, subtract 34 from both sides: s = 54 - 34, so s = 20.

Front

What operation would you use to solve the equation x - 5 = 10?

Back

You would add 5 to both sides to isolate x: x = 10 + 5, so x = 15.

Front

What is the solution to the equation 3y = 12?

Back

To solve for y, divide both sides by 3: y = 12 / 3, so y = 4.

Front

How do you check the solution of an equation?

Back

Substitute the solution back into the original equation to see if both sides are equal.

Front

What is the inverse operation of addition?

Back

The inverse operation of addition is subtraction.
