Well they both have integers in it there the same thing except your adding and subtracting. <span>Subtraction is the same thing as adding the opposite of the number. </span>
left means subtracting
6 7/8 - 2 5/8
Whole numbers subtract each other
Numerators subtract each other
The denominators stay the same.
6-2= 4
7-5=2
4 2/8
Reduce 2/8. Divide by 2. 2/2= 1, 8/2= 4
4 2/8=4 1/4
Answer: 4 2/8 = 4 1/4 cups left
Answer:
1st Equation: -8x + y = 22
At (-2,6)
(-8*-2)+ 6 =16+6= 22: That is correct
2nd Equation: -8x - y =10
At (-2,6)
(-8*-2)-6= 16-6= 10: That is correct
Both are correct.
Hope it helps you.
