Answer:
One Solution
Step-by-step explanation:
First substitute the y in the first equation with the second equation to get
-2x-4=3x+3
since theres a variable of both sides, you subtract the variable with the least coefficient, in this case, you add 2x to both sides to get
-4=5x+3
subtract the constant on both sides to get
-1=5x
divide both sides by 5
x= -0.2 or -1/5
To find the percentage divide 10 by 100.. each chapter would make up 10% of the book.
The LCD here is 12(5) = 60.
We must rewrite <span>7/12 - 2/5 with 60 as common denominator.
Doing this, we get 35/60 - 24/60 = 11/60 (answer)</span>
