add them together then divide by 5
81 +86 +81 +76 +71 = 395
395/5 = 79
your average was 79
Answer:
so basically is right how you write but multiplication goes first
X+y=62 ; x-y=12 Solve for x in one equation and plug that value into the other equation. ===> x=12+y ; 12+y+y=62 Subtract 12 to both sides (2y=50), then divide by 2 to find y (y=25). Now, plug 25 as y into x=12+y, getting x=37. Your two numbers are 37 and 25.
