Step-by-step explanation:
x = x + 22 - 8
x = x + 14
x = x + 14
x - x = x + 14 - x

So 1 gallon of window cleaner
1 part is cleaner
3 part is water
so therefor
1/(1+3)=1/4=cleaner
3/4=water
1 gallon=4 quarts
1 quart cleaner
3 quart water
1 quart
2x + 3/12 = 2x/8
2x - 2x/8 = -3/12
2x - x/4 = -3/12; 2 - 1/4 = 1 3/4 = 7/4
7x/4 = -3/12
7x = -3/12 * 4
7x = -1
x = -1/7
