Find the value of the variable which satisfies the equation. 1. 4a - 5 = 11 2. 16 = 17 - r 3. 8 = n/4 - 6 4. b/4 + 7 = 9 5. 12c + 6c = 36 6. 14x + 11x + 10 = 85 7. 19w - 13 - 6w = -39 8. -4(2n – 5) = -28 9. 8y + 3(12 – 7y) = 49 10. -18 = 15z - 9(2z – 2) Solve an equation to find the number. 11. The difference of six times a number and 7 is -49. 12. Negative sixteen plus the quotient of a number and -4 is –3. 13. The sum of two times a number and 11 is -7. 14. The total cost for a week at camp is $220. You have $140. You earn $16 for every item you sell in a fundraiser. How many items do you need to sell to pay for a week at camp?

Step 1
- Add 5 to both sides of the equation to isolate the term with the variable: 4a - 5 + 5 = 11 + 5. - This simplifies to 4a = 16. - Divide both sides by 4 to solve for a: 4a / 4 = 16 / 4. - This gives us a = 4. Show more…
