1.4 Variables on Both Sides HW

The objective when solving an equation is to....

• isolate the variable.
• check the solution.
• guess and check.
• Combine Like Terms.

Which of the following are examples of like terms?

• 2 and 2x
• y³ and x³
• y and x
• -3x and 3x

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

Solve for x.

• 55
• 60
• 15
• 35

What is the first step in the equation:

2x - 3 + 4x = 27

• Combine Like Terms

• Add 3 on both sides

• Divide by 2 on both sides

• Subtract 4x from both sides

What will the equation look like after you combine like terms?

• -5x + 5 = 35

• x + 5 = 35

• 5x + 5 = 35

• -x + 5 = 35

What is the first step in solving this equation?

• add 4 to both sides

• distribute the 4

• subtract 4 to both sides

• subtract 12 to both sides

What is the first step you should take to solve this problem?

1 + 4n - 6n = 1 - 8n

• subtract 8n to both sides

• multiply 6n to both sides

• combine the like terms: 4n & -6n

What is the next step you should take?

1 + 4n = 10 - 14n

• add 14n to both sides

• combine 4n and -14n

• subtract 14n to both sides

What is the next step you should take?

1 + 18n = 33

• subtract 1 to both sides

• collect the numbers to the right

• add 1 to both sides

• multiply 18 to both sides
