Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
2x - 9y = 11
<em>x</em> = 7
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: 2(7) - 9y = 11
- Multiply: 14 - 9y = 11
- [Subtraction Property of Equality] Subtract 14 on both sides: -9y = -3
- [Division Property of Equality] Divide -9 on both sides: y = 1/3
Answer:
The number is 86
Step-by-step explanation:
Let the number be
, then the reverse is 
The sum of the reversed number and the original number is 154,

We simplify this to get:
....eqn(1)
If the ones digit in it is 2 less than the tens digit, then
....eqn(2)
Putt equation (2) in (1)





Put x=8 in the second equation:

The original number is 86
The nth term is 9n-3. The 10th term is 87 and the 75th term is 642.
