<span>We have 75 mL of 4% sugar solution.
We have to add a 30% sugar </span><span>solution to make a 50% </span><span>sugar solution.
75 * .04 + .30x = .50 * (75 +x)
3 + .30x = 37.5 +.50x
I can't get the equation to solve.
Did you type it correctly? For one thing, you have the percentages typed as .30 % and 4%. Are the decimal places in the correct positions?
Also, no matter how much 30% sugar solution you add, it will NEVER increase to 50%.

Answer:
x=3/2, y=10. (3/2, 10).
Step-by-step explanation:
2x-y=-7
4x-y=-4
--------------
-2(2x-y)=-2(-7)
4x-y=-4
---------------------
-4x+2y=14
4x-y=-4
-----------------
y=10
2x-10=-7
2x=-7+10
2x=3
x=3/2
