Answer: hope this helps
Step-by-step explanation:
Write down the numbers, one under the other, with the decimal points lined up.
Put in zeros so the numbers have the same length (see below for why that is OK)
Then add, using column addition, remembering to put the decimal point in the answer.
Answer:
y=-4
y+6=2
y=2-6
23
25
substitute 17 for A
substitute 8 for B
should look like this
17+8
then add
17+8=25
-2 <em>1/3</em>
((4 * 3) - (-2) /(-2*3)
(12 + 2 ) / (-2 * 3)
14 / -6
