For every 3 bottles of water sold at a gas station, there are 4 bottles of soda sold. if there are 20 more bottles of soda sold than water in a day, how many bottles of water were sold?

A) w / s = 3 / 4  OR A) 4w = 3s

B) w + 20 = s then multiplying B) by -4

B) -4w -80 = -4s  then adding it to A)

A) 4w = 3s

-80 = -s

So 80 bottles of soda and

60 bottles of water were sold

DOUBLE-CHECK

60/80 = 3/4 and 80 -60 = 20  correct!!

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
