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

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

he answer is x=1x3 because x=1 to x=3
