Value of x: 2.5
Value of y: -0.5
-------------------------
To find x:
x + 1 = 3x - 4
-x -x
1 = 2x - 4
+4 +4
5 = 2x
-- ---
2 2
2.5 = x
Check:
2.5 + 1 = 3(2.5) - 4
3.5 = 7.5 - 4
3.5 = 3.5
To find y:
3y = 5y + 1
-5y -5y
-2y = 1
--- ----
-2 -2
y = -0.5
Check:
3(-0.5) = 5(-0.5) + 1
-1.5 = -2.5 + 1
-1.5 = -1.5
In mass or percent weight (%w); the concentration would be :
![100 * \frac{MassSolute}{MassSolution} = PercentWeight](https://tex.z-dn.net/?f=100%20%2A%20%20%5Cfrac%7BMassSolute%7D%7BMassSolution%7D%20%3D%20PercentWeight%20)
100 * 50 / (50 + 30) = 100 * 50/80 = 62.5 %w
The scientific notation for 14,200,00= 1.42x10^6
