Question 553655
If x = the total capacity of the cylindrical vessel in liters, then:
{{{(1/4)x+7 = (3/5)x}}} Simplify and solve for x. Multiply through by 20 to clear the fractions.
{{{20(1/4)x+20(7) = 20(3/5)x}}} Simplify.
{{{5x+140 = 12x}}} Subtract 5x from both sides.
{{{140 = 7x}}} Divide by 7.
{{{20 = x}}}
The total capacity is 20 liters.
