Paybeginning $1,032 - $150 = $882.56* 1.00938 = $ 890.84
Pay end $1,032.56 * 1.00938 = $1042.25- $150 = $892.25
The difference is in interest in the first month 892.25−890.25=2
Note: 11.25 / 12 = 0.00938 interest per month
Answer:

Step-by-step explanation:
1. expand.

2. Subtract 8x from both sides.

3. simplify 10x - 2 - 8x to 2x - 2.

4. Add 2 to both sides.

5. Simplify 6+2 to 8.

6. Divide both sides by 2.

7. Simplify 8/2 to 4.

8. switch sides.

Therefor, rhe answer is x=4
