3/4z = 2/3a
z + a = 510...z = 510 - a
3/4(510 - a) = 2/3a
382.50 - 3/4a = 2/3a
382.50 = 2/3a + 3/4a
382.50 = 8/12a + 9/12a
382.50 = 17/12a
382.50 * 12/17 = a
270 = a
z + a = 510
z + 270 = 510
z = 510 - 270
z = 240
check..
3/4z = 2/3a
3/4(240) = 2/3(270)
180 = 180 (correct)
Zul had $ 240
Zul gave 30% of his money to his sister
0.30(240) = 72
his sister received $ 72

liters is the amount to be drained out and replaced
<em><u>Solution:</u></em>
40 % antifreeze solution in 16 liter radiator
Let "x" be the amount drained from radiation and replaced with pure antifreeze
To obtain a 60 % antifreeze solution
The original solution is 16 liter, 40% of which is antifreeze
You want the solution to be 60% antifreeze:
60 % x 16 =
You will remove x liters of the 40% solution and replace it with x liters pure (100%) antifreeze.
Let us solve expression for "x"
Thus liters is the amount to be drained out and replaced
