6x + 4y = -14<br> -X-5y=11
kumpel [21]

Answer:

x= -1; y= -2

A:   6x+4y= -14  

B:  -x-5y=11

6B is :  -6x-30y=66

A+6B is :  -26y=52

so x= -1

Lydias hotel room number has three digits.The hundreds digit has a value of 40 Tens.The Tens digit is greater than 6. Which coul
stiks02 [169]

Any 3 digit number can be expressed in the form of:

(a*100)+(b*10)+(c*1)

Where a, b, c represent any natural number from 0 to 9.

We are told the hundreds number (this means a*100 in the expression above) is equal to the value of 40 tens, 40 tens is 400. Then, we know the digit in the tens is greater then 6, this means b>6 in the expression above.

So, there are multiple numbers the room number could be, namely:

400+(b*10)+(c*1)\\

where b can be 7, 8, or 9; and c can be  0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. So, there's 30 possible room numbers Lydia may be.
