Solving One-Step Equations with Addition and Subtraction

What is a solution in the context of algebraic equations?

• A formula to calculate variables

• A value that satisfies the equation

• A value that makes the equation incorrect

• A method to simplify expressions

If p + 10 = 38 and p is 18, is 18 a solution to the equation?

• No, because 18 + 10 is not 38

• Yes, because 18 + 10 is less than 38

• Yes, because 18 + 10 = 38

• No, because 18 is too high

What does it mean for an equation to be balanced?

• Both sides have the same number of terms

• The mathematical operations are visible

• Both sides of the equation are equal in value

• It contains both addition and subtraction

In the scale analogy, what happens if you perform the same operation on both sides?

• The scale remains balanced

• The scale tips to one side

• The scale becomes invalid

• The scale automatically resets

How do you solve the equation x - 2 = 6?

• Divide both sides by 2

• Subtract 2 from 6

• Add 2 to both sides

• Multiply both sides by 2

What is the solution to the equation x - 2 = 6?

• x = 3

• x = 6

• x = 8

• x = 4

When solving 18 = x - 7, what operation is used to isolate x?

• Multiplication

• Addition

• Subtraction

• Division

What is the value of x when solving the equation 18 = x - 7?

• x = 11

• x = 7

• x = 25

• x = 18

What operation is used to solve the equation x + 13 = 27?

• Addition

• Subtraction

• Division

• Multiplication

What is the solution to x + 13 = 27?

• x = 14

• x = 13

• x = 40

• x = 20
