Fourteen subtracted from the sum of double a number and six

Algebraic expression

Sum= addition

lets set the problem up like this

and let the first number equal A and the second number is B

This what we know:

14 = (a ) + 2(B)

A - B = 2

We need to find A and B

Step-by-step explanation:

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

answer: y=0 if that is what u r looking for
