15 minus 9 is equal to 6 <span />
Multiply -2 with x equaling -2x
Multiply -2 with +6 equaling -12
Y - 5 = -2x - 12
Add 12 on both sides
Y - 5 + 12 = -2x - 12 + 12
Y + 7 = -2x
Divide by -2 on both sides
Y + 7 / -2 = -2x/-2
Y + 7
------- = x
- 2
Answer:

Answer:
(A) 66k+9
Step-by-step explanation:
50k+5+4+16k
3b+5r=2 gallons of cabbage red
1r+7b=2gallons of egplant
1 gallon of cabbage sells for 22 (means 2 gallos is 44)
1 gallon of egplant is 26 (means 2 gallons is 52)
3b+5r=44
r+7b=52
r+7b=52
miinus 7b from both sides
r=52-7b
sub 52-7b for r in othe equestion
3b+5(52-7b)=44
3b+260-35b=44
-32b+260=44
minus 260 from both sides
-32b=-216
divide both sides by -32
b=6.75
r=52-7b
r=52-7(6.75)
r=52-47.25
r=4.75
3blue+5r=2gallons
5+3=8
8units=2gallons
4units=1gallon
1unit=1quart
therefor
1 quart of blue paint is $6.75
1 quart of red paint is $4.75
