Step-by-step explanation:
3x-3y=6
-6x+6y=-12
------------------
2(3x-3y)=2(6)
-6x+6y=-12
-------------------
6x-6y=12
-6x+6y=-12
--------------------
0=0
D + q = 40
.10d +.25q= $7.75
d +q = 40
d =40-q
.10(40-q) +.25q= $7.75
4 - .10q + .25q =7.75
4 +.15q =7.75
4-4 +.15q =7.75-4
.15q= 3.75
.15q/.15 = 3.75/.15
q = 25
d =40-25
d = 15
Check
.10(15) +.25(25)= $7.75
1.5+6.25=7.75
7.75=7.75
