Answer:
500 - 368 = 132This means that to reach 500 from 368, you will need to count 132 ones.132 can be written in several ways including:132 = 100 + 32132 = 100 + 30 + 2For the first one:the count will be 1 one hundred and 32 units to reach 500 from 368For the second one:the count will be one hundred, 30 tens and 2 ones to reach 500 from 368

Answer:
x = -6/5
y =7/5
Step-by-step explanation:
2x + y = - 1
x - 2y = - 4
Multiply the first equation by 2 so we can eliminate y
2(2x + y = - 1)
4x + 2y = -2
Add this to the second equation
4x + 2y = -2
x - 2y = - 4
---------------------
5x + 0y = -6
Divide by 5
5x/5 = -6/5
x = -6/5
Multiply the second equation by -2 so we can eliminate x
-2(x - 2y = - 4)
-2x+4y = 8
Add this to the first equation
2x + y = - 1
-2x+4y = 8
---------------------
0x + 5y = 7
Divide by 5
5y/5 = 7/5
y =7/5
