# What will be the Value of x+y? If

999x+888y=1332

888x+999y=555

- 888
- 1
- 2x
- 2

**Answer: (2) 1**

**Explanation:-**

999x + 888y = 1332

divide by 111 from both side,

9x + 8y = 12 ………………………………… (1)

Again,

888x + 999y = 555

divide by 111 from both side,

Then, 8x + 9y = 5 …………………….. (2)

Solve equation (1) & (2)

x = 4 & y = -3

Then, x + y = 4 + (-3) = 4 – 3 = 1

Hence, the answer is (2) 1.
