Solving Equations Using Addition and Subtraction

The video tutorial covers solving equations using addition and subtraction. It explains how to determine if a given value is a solution to an equation by checking if it balances the equation. Two examples are provided: one where a value is not a solution and another where it is. The process involves substituting the given value into the equation and verifying if both sides are equal.

What does it mean for a value to be a solution to an equation?

• It makes the equation false.

• It keeps the equation balanced.

• It changes the equation.

• It has no effect on the equation.

If p = 18, what is the result of p + 10?

• 48

• 28

• 38

• 18

CCSS.6.EE.B.5

Why is p = 18 not a solution for the equation p + 10 = 38?

• Because 18 + 10 is not equal to 38.

• Because 18 is too small.

• Because 18 is too large.

• Because 18 is not a number.
