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 one operation, either by addition or subtraction.

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 n + 3.5 = 6.7?

Back

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

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 5 = m + 11?

Back

Subtract 11 from both sides: m = 5 - 11, so m = -6.

Front

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

Back

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

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 + 4 = 10?

Back

Subtract 4 from both sides: x = 10 - 4.

Front

What is the solution to the equation y - 5 = 3?

Back

Add 5 to both sides: y = 3 + 5, so y = 8.

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.
