b)
3x +
2y = 12
x - y = -1

3x+2y=12

x-y= -1 ( this shows that y is greater than x as during subtraction, the answer takes up the integer of the biggest number in the expression)

since, we know that x is greater than y, lets check if the numbers, x being small and y being big gives , 3x+2y=12.

start from 1 and 2, 2 and 3, 3 and 4, 4 and 5, 5 and 6, 6 and 7, 7 and 8, 8 and 9, 9 and 10, 10 and 11, finally 11 and 12.

1) 3+4=7  not equal to 12

2) 3*2+2*3=6+6=12

3)9+8= 17 not equal to 12

4)12+10=22 not equal to 12

5) 15+12= 27 not equal to 12

6) 18+14=32 not equal to 12

7) 21+16= 37 not equal to 12

8) 24+18= 42 not equal to 12

9) 27+ 20=47 not equal to 12

10)30+22=52 not equal to 12

11) 33+24=57

here, only 2 and 3 can replace x and y, so we get that 3*2+2*3=12

step-by-step explanation:

use that smart brain

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
