Answer:
Intersect/Solution at (1, -2)
Step-by-step explanation:
Equation 1: y = 3x - 5
Equation 2: y = 6x - 8
Step 1 Mutliply each side of equations one by -2
New Equation 1: -2y = -6x + 10
New Equation 2: y = 6x -8
Add the Equations: -y = +2
Multiply each side by -1 and you'll get that y = -2
Plug in -2 to either equation: -2 = 3x - 5
add 2 to each side 0 = 3x -3
add 3 to each side 3x = 3
divide by 3 and you'll get that x = 1
Part A:The solution of the pair of the equation is,x=1 and y=- -2.
Part B: If the two equations are graphed, at point (1,-2) will the lines representing the two equations intersect.
How to get the slope intercept form of a straight line equation?If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:
y = mx +c
A pair of equations is shown below:
y = 3x − 5 -------1
y = 6x − 8 --------2
Substitute the value of y from the equation 1 into equation 2;
3x − 5=6x − 8
3x=-5+8
3x=3
x=1
Put the value of x in the equation 1;
y = 3x − 5 -------1
y=3(1)-5
y=- -2
Hence,the solution of the pair of the equation is,x=1 and y=- -2 and at point (1,-2) will the lines representing the two equations intersect.

30 books on the shelf are Fiction.
Step-by-step explanation:
Hey!
There are 50 books on a shelf.
1/5 of the books are Science Fiction.3/10 are Non-Fiction.The Rest are Fiction.how many books on the shelf are Fiction?
==================================================================
MAKE AN EQUATION!
We know that there are three Categories: Fiction, Science Fiction, and Non Fiction.
Total- 50
⇒ 50 =
1/5 of 50 are SF
⇒ 50 = (1/5)(50)
3/10 of 50 are NF
⇒ 50 = (1/5)(50) + (3/10)(50) + x
--------------------------------------------------------------------------------------------------------------
SOLVE THE EQUATION!
(1/5)(50) + (3/10)(50) + x = 50
To Isolate X-
-Multiply and remove the parentheses..
⇒ 50/10 + 150/10 + x = 50
-Simplify.
⇒ 5 + 15 + x = 50
-Add Like Terms
⇒ 20 + x = 50
-Subtract 20 from both sides.
⇒ 20 + x - 20 = 50 - 20
-Simplify Right Hand Side.
⇒ x = 30
--------------------------------------------------------------------------------------------------------------
So, 30 books on the shelf are Fiction.
