6n-15=n
minus n both sides
5n-15=0
add 15 both sides
5n=15
divide both sides by 5
n=3
de number is 3

Answer: y=x
The slope of the perpendicular line is the opposite reciprocal. So you do -(-1/1) which equals 1. So now we have y=x+b. Plug (3,3) into this and you get 3=3+b. So b=0 and the equation is y=x
SOLUTION:
by putting x = 4y - 1 in the equation x + 2y = 11, we get;
=) 4y - 1 + 2y = 11
=) 6y = 11 + 1
=) y = 12/6
=) y = 2
Now that we got the value of y we can put the value in the equation x = 4y - 1.
=) x = 4(2) - 1
=) x = 8 - 1
=) x = 7
Hence, the value of x is 7 and y is 2.
