Answer:
Step-by-step explanation:
The given expression is x- 
= 2
and we have to solve this for the value of x,
( x- ) = (2)
x² - 15 = 2x
x² - 2x - 15 = 0
x² - 5x + 3x - 15 = 0
x ( x-5 ) + 3(x - 5) = 0
( x+3 )( x-5 ) = 0
( x+3) = 0
x = -3
or ( x- 5 ) = 0
x = 5
Therefore, x = -3 and 5 will be the solution.
Option E is the answer.

Answer:
17(n+31)=300
Step-by-step explanation:
17 times the sum of a number, n and 31 is 17(n+31)
and then set that equal to 300
They are supplementary angle and adjacent agles
It all depends on the importance of the variable its self. Its important to solve it so you know what the variable is and its important to solve one at a time because its impossible to solve a variable completely if you have two of them
