giulio has 24 pencils so he can equally put them into 2 groups of 12, while george has 35.
or think of it as -2+3=1, subtract 1 from both sides so -2-1=-3
16 packages of muffins
1) first you need to find out how many muffins you need total. if each person has two muffins and there are 48 people, how muffins would that be? to find out, multiply 48 and 2 together.
48 * 2 = 96
so now we know that we must have 96 muffins in total
2) now we have to find out how many muffin packages we will need. if there are 6 muffins in each package and we need to have 96 muffins in total, how many packages will we need? to find out, divide 96 by 6.
96/6 = 16
from this we know that you will need 16 packages
let's call 8x-6 a and
2xsq - 3x + 5 b
so in the left column the first equations simplifies out to a
the second equation in the left column simplifies out to a
the third equation in the leftcolumn simplifies out to b
in the right column the first equation simplifies out to b
in the second equation right column simplifies out to b
