One Step equations addition and subtraction

Front

What is a one-step equation?

Back

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

How do you solve the equation x + 2 = 8?

Back

To solve x + 2 = 8, subtract 2 from both sides to isolate x: x = 8 - 2, so x = 6.

What is the first step to solve the equation 2 = z - 14?

Back

The first step is to add 14 to both sides of the equation to isolate z: z = 2 + 14, so z = 16.

How do you isolate the variable in the equation p - 11 = -5?

Back

To isolate p, add 11 to both sides: p = -5 + 11, so p = 6.

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

Back

To solve for t, add 18 to both sides: t = 98 + 18, so t = 116.

Front

How do you solve the equation 12 = g - 56?

Back

To solve for g, add 56 to both sides: g = 12 + 56, so g = 68.

Front

What is the principle of balancing equations in algebra?

Back

The principle of balancing equations states that whatever you do to one side of the equation, you must do to the other side to maintain equality.

Front

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

Back

Isolating a variable means manipulating the equation so that the variable is on one side by itself, allowing you to find its value.
