Question

11. Solve the equation n/10 + 7 = 10

Answer 1

n = 30

Explanation:

Step 1: Subtract 7 from both sides.

• 
  `(n)/(10) + 7 - 7 = 10 - 7`
• 
  `(n)/(10) = 3`

Step 2: Multiply both sides by 10.

• 
  `(n)/(10) * 10 = 3 * 10`
• 
  `n = 30`

Step 3: Check if solution is correct.

• 
  `(30)/(10) + 7 = 10`
• 
  `3 + 7 = 10`
• 
  `10 = 10`

Therefore, n = 30.
