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.

In the equation p + 10 = 38, what should p be to make it a solution?

• 38

• 10

• 18

• 28

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

• 48

• 28

• 38

• 18

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.

In the equation 4y = 56, what operation is implied between 4 and y?

• Division

• Multiplication

• Subtraction

• Addition

What is the value of y that makes 4y = 56 a true statement?

• 12

• 13

• 14

• 15

What is the result of 4 times 14?

• 60

• 58

• 56

• 54

What does it mean if both sides of an equation are balanced?

• The equation is incorrect.

• The equation is a solution.

• The equation is unsolvable.

• The equation is incomplete.

What should you do if the sides of an equation are not balanced?

• Conclude it is not a solution.

• Add more numbers.

• Change the equation.

• Ignore the equation.

What is the key step in verifying if a value is a solution to an equation?

• Ignoring the equation.

• Changing the equation.

• Balancing both sides of the equation.

• Guessing the value.
