You need to graph it?
5x - 2y = 7
you need two points to graph a line
make x = 0
5(0) - 2y = 7
-2y = 7
/-2 /-2
y = 7/-2 (0, -7/2)
make y = 0
5x - 2(0) = 7
5x = 7
/7 /7
x = 7/5 (7/5, 0)
make those points and join them

Answer:
= x + y + 20
Step-by-step explanation:
There are a couple of ways you could write this.
friend sales + your sales
= (14 +x) +(y +6)
= (x +14) +(6 +y) . . . . commutative property used twice
= x +14 +6 +y = x +20 +y
= x + y + 20 . . . . . . . commutative property used again
__
first-day sales + second-day sales
= (14 +y) + (x +6)
= (y +14) +(6 +x) . . . . commutative property used twice
= y +14 +6 +x = y +20 +x
= y +x +20 . . . . . . . . commutative property used again
= x + y + 20 . . . . . . . and again

<em>Additional comment</em>
We also used the associative property (to move parentheses) and the properties of addition of integers to simplify the sum. We have chosen to put the variables in lexicographical order, a sort of standard.
