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 performing either addition or subtraction to isolate the variable.

Front

How do you solve the equation 2 = z – 14?

Back

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

Front

What is the solution to the equation 98 = t – 18?

Back

Add 18 to both sides: 98 + 18 = t, so t = 116.

Front

How do you solve the equation d – 10 = 8?

Back

Add 10 to both sides: d = 8 + 10, so d = 18.

Front

What is the solution to the equation p – 11 = -5?

Back

Add 11 to both sides: p = -5 + 11, so p = 6.

Front

How do you solve the equation 86 + y = 99?

Back

Subtract 86 from both sides: y = 99 - 86, so y = 13.

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 z + 5 = 12?

Back

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

Front

What is the solution to the equation x - 4 = 10?

Back

Add 4 to both sides: x = 10 + 4, so x = 14.

Front

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations are used to undo the operations applied to the variable, helping to isolate it.
