Answer:
1) x = 6
2) x = 4.5 or 9/2
3) x = 35
4) x = 13
Step-by-step explanation:
Question 1) Divide both sides by 3. 18 divided by 3 is 6.
Question 2) Divide both sides by 2. 9 divided by 2 is 4.5 or 9/2.
Question 3) Multiply both sides by 5. 7 times 5 is 35.
Question 4) Multiply both sides by 2. 6.5 times 2 is 13.
