One Step equations addition and subtraction

Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single step, usually by adding or subtracting a number from both sides.

Front

How do you solve the equation n + 3.5 = 6.7?

Back

Subtract 3.5 from both sides: n = 6.7 - 3.5, so n = 3.2.

Front

What is the solution to the equation 72 = 24 + w?

Back

Subtract 24 from both sides: w = 72 - 24, so w = 48.

Front

How do you solve the equation 16 = n + 6?

Back

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

Front

What is the solution to the equation 2 = z - 14?

Back

Add 14 to both sides: z = 2 + 14, so z = 16.

Front

How do you solve the equation x + 1.6 = 0.8?

Back

Subtract 1.6 from both sides: x = 0.8 - 1.6, so x = -0.8.

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 to find its value.

Front

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

Back

Subtract 5 from both sides: n = 12 - 5.

Front

What is the solution to the equation 50 = m + 20?

Back

Subtract 20 from both sides: m = 50 - 20, so m = 30.

Front

How do you solve the equation 10 = p - 3?

Back

Add 3 to both sides: p = 10 + 3, so p = 13.
