Answer:
Step-by-step explanation:
3x +2y = 13 -----------------(i)
x + 2y = 7 ----------------(ii)
Multiply the equation (ii) by (-1) and then add.
(i) 3x + 2y = 13
(ii)*(-1) <u>-x - 2y = -7 </u> {Now, add and y will be eliminated}
2x = 6
x = 6/2
x = 3
Plug in x = 3 in equation (i)
3*3 + 2y = 13
9 + 2y = 13
2y= 13 - 9
2y = 4
y = 4/2
y = 2

Answer:
The smallest of the said odd numbers is 27
Step-by-step explanation:
Since it is 3 odd numbers that sums up to 87, the first thing to do is to divide 87 by 3
That is 87/3 = 29, which is an odd number
The nearest odd numbers to 29 are 27 and 31, and the total of all these three odd numbers is 87
That is 27+29+31 = 87, which are consecutive odd numbers.
The smallest odd number here is therefore 27
