Answer:
x = -1, y = 1
Step-by-step explanation:
Given that:
Isolate x for 4x + 11y = 7 which ⇒
Substitute into the equation: which is:
Drop Down to:
Isolate y for 7-8y = -1: y = 1
Thus,
Substitute y = 1

Here is how I completed the problem:
I started by creating a ratio:
<em>Where 'x' is the desired amount of the 18% solution of sulfuric acid.
</em>From here, I solved for 'x':
<em>
</em>
∴You will need to add 1080ml of 18% Sulfuric Acid in order to obtain a 15% solution.
