1. A number minus 6 is – 22.
Find the number,

-16

Step-by-step explanation:

X-6= -22

X = -22+6

X = - 16

The number is - 16

Step-by-step explanation:

A number: n

n - 6 = -22

  + 6     +6

n = -16

Check your

n - 6 = -22

-16 - 6 = -22

-22 = -22

This statement is true

Hope this helps!

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
