Melissa went to shopping and spent 2/3 of her money on a blouse, then she has 1/3 of her money left. She came home with $12.
=> The amount of money she started with: 12 x 3 =36$
Hope this helps!

The linear equation in slope intercept form: y = mx + b.
We have:
![2x+5xy-3=0\qquad\text{subtract 2x from both sides}\\\\5xy-3=-2x\qquad\text{add 3 to both sides}\\\\5xy=-2x+3\qquad\text{divide both sides by}\ 5x\neq0\\\\y=\dfrac{-2x+3}{5x}](https://tex.z-dn.net/?f=2x%2B5xy-3%3D0%5Cqquad%5Ctext%7Bsubtract%202x%20from%20both%20sides%7D%5C%5C%5C%5C5xy-3%3D-2x%5Cqquad%5Ctext%7Badd%203%20to%20both%20sides%7D%5C%5C%5C%5C5xy%3D-2x%2B3%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%7D%5C%205x%5Cneq0%5C%5C%5C%5Cy%3D%5Cdfrac%7B-2x%2B3%7D%7B5x%7D)
This is not a linear equation.
Given solution: should be solution.
8p (>/=) -7 8p (>/=) -78p (>/=)-7 8p (>/=) -7 SAME
8p/8 (=) -7/8 8p/8 (>/=) -7/8 DIFFERENT
p (=) -7/8 p (>/=) -7/8 DIFFERENT
The error in the given solution was that the inequality sign > was taken out of the equation. It should not be because the expression is an inequality. p can be any number that is greater than or equal to -7/8. It is not limited to only -7/8.
