If y is equal to 2 then you can find x by putting 2 for y so you will have:
2x + 8(2) = 20
2x + 16 = 20
2x = 20 - 16
2x = 4
x = 4/2
x=2 :)))
i hope this is helpful

2x + 8y = 20
y = 2

Substitute y with its value.

2x + 8y = 20
2x + 8(2) = 20
2x + 16 = 20
2x = 20 - 16
2x = 4
x = 4/2
x = 2

x = 2; y = 2

2x + 8y = 20
2(2) + 8(2) = 20
4 + 16 = 20
20 = 20

Alexus [3.1K]

1 liter=.26 gallons so 20 liters= 20*.26= 5.2 gallons.

You need to use .75 ounces of soda ash per gallon so you must multiply .75 by 5.2.

.75*5.2 = 3.9 ounces
