One Step Equations with Decimals

Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single step by performing the same operation on both sides to isolate the variable.

Front

How do you solve for x in the equation x + a = b?

Back

To solve for x, subtract a from both sides: x = b - a.

Front

How do you solve for x in the equation x - a = b?

Back

To solve for x, add a to both sides: x = b + a.

Front

How do you solve for x in the equation x/a = b?

Back

To solve for x, multiply both sides by a: x = a * b.

Front

How do you solve for x in the equation x = b/a?

Back

To solve for x, divide b by a: x = b / a.

Front

What is the first step to solve the equation 1.6 = x/3.9?

Back

Multiply both sides by 3.9 to isolate x.

Front

What is the solution to the equation x/4.3 = 10.9?

Back

x = 10.9 * 4.3 = 46.87.

Front

What is the solution to the equation x - 7.09 = 10.89?

Back

x = 10.89 + 7.09 = 17.98.

Front

What is the solution to the equation x + 100.45 = 200.19?

Back

x = 200.19 - 100.45 = 99.74.

Front

What is the solution to the equation x + 4.2 = 18.5?

Back

x = 18.5 - 4.2 = 14.3.
