In commutative property , we can add numbers in any order.
Here we are given with fractions
We can add or subtract fractions in any order
We change the order of fraction that has same denominator so that we can add it more easily using commutative property
The first two fractions have same negative sign and common denominator
so we add it
Simplify the fraction 12/ 16
Add the fractions

Let Edy's money be x.
Lucy: 35% more --- (135/100) x
x + (135/100) x = 206.80
(47/20)x = 206.80
47x = 206.8 x 20
47x =4136
x = 88
Edy saved $88.
Lucy saved (135/100)(88) = $118.80
Yas! systems of equations
convert one equation so that a single variable is one one side
x = 65 - 2y
plug it in the other equation
2(65 - 2y) + 3y = 105
130 - 4y + 3y = 105
130 - y = 105
25 = y
