Practice on Solve one Step equations (Addition)

Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single step, typically involving addition or subtraction.

Front

How do you solve the equation r + 20 = 27?

Back

Subtract 20 from both sides: r = 27 - 20, so r = 7.

Front

What is the solution to the equation a + 2 = 16?

Back

Subtract 2 from both sides: a = 16 - 2, so a = 14.

Front

How do you solve the equation x + 9 = 17?

Back

Subtract 9 from both sides: x = 17 - 9, so x = 8.

Front

What is the value of V in the equation V + 23 = 45?

Back

Subtract 23 from both sides: V = 45 - 23, so V = 22.

Front

How do you solve the equation 15 = 4 + x?

Back

Subtract 4 from both sides: x = 15 - 4, so x = 11.

Front

What is the inverse operation of addition?

Back

The inverse operation of addition is subtraction.

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means to get the variable alone on one side of the equation.

Front

What is the first step in solving the equation x + 5 = 12?

Back

Subtract 5 from both sides to isolate x.

Front

If you have the equation y + 10 = 25, what is y?

Back

Subtract 10 from both sides: y = 25 - 10, so y = 15.
