Understanding Two-Step Equations

What is the first step in solving the equation 2x + 2 = 8?

• Divide both sides by 2

• Multiply both sides by 2

• Subtract 2 from both sides

• Add 2 to both sides

After subtracting 2 from both sides in the equation 2x + 2 = 8, what is the next step?

• Multiply both sides by 2

• Divide both sides by 2

• Subtract 2 again

• Add 2 to both sides

In the equation x/2 - 1 = 4, what operation is undone first?

• Subtraction

• Addition

• Multiplication

• Division

What is the result of x in the equation x/2 - 1 = 4 after solving?

• x = 8

• x = 5

• x = 3

• x = 10

How does the presence of parentheses affect the order of operations in solving equations?

• Operations inside parentheses are undone last

• Parentheses do not affect the order

• Operations inside parentheses are done last

• Operations inside parentheses are undone first

What is the final value of x in the equation with the group (x + 2) multiplied by 2, set equal to 8?

• x = 4

• x = 2

• x = 5

• x = 3

In the equation with x - 1 over 2 equals 4, what is the first operation to undo?

• Multiplication

• Division

• Addition

• Subtraction

What does the fraction line imply in algebraic expressions?

• Grouping of terms above and below it

• Only division is implied

• No specific implication

• Only multiplication is implied

After multiplying both sides by 2 in the equation with x - 1 over 2 equals 4, what is the next step?

• Add 1 to both sides

• Subtract 1 from both sides

• Multiply both sides by 2 again

• Divide both sides by 2

What is the final value of x in the equation where x - 1 over 2 equals 4, after solving?

• x = 9

• x = 8

• x = 10

• x = 11
