Answer:
Step-by-step explanation:
A salt solution contains 10% salt and weights 80g.
<u>Salt content of the solution is:</u>
<u>4% solution has 8 g salt, total solution is:</u>
- 0.04x = 8
- x = 8/0.04 = 200 g
<u>Water to be added:</u>
4-3=1 and 5-4= 1 so it's 4
4 = 4x (original equation)
4/4 = 4x/4 (divide both sides by 4)
1 = x (simplify)
Make sure that you're doing the same things to each value on BOTH sides. This keeps the equation true. Once you do that, you should get that x is equal to 1.
