Answer:
n = 30
Step-by-step explanation:
Step 1: Subtract 7 from both sides.
- [tex]\frac{n}{10} + 7 - 7 = 10 - 7[/tex]
- [tex]\frac{n}{10} = 3[/tex]
Step 2: Multiply both sides by 10.
- [tex]\frac{n}{10} * 10 = 3 * 10[/tex]
- [tex]n = 30[/tex]
Step 3: Check if solution is correct.
- [tex]\frac{30}{10} + 7 = 10[/tex]
- [tex]3 + 7 = 10[/tex]
- [tex]10 = 10[/tex]
Therefore, n = 30.
