Combine all like terms and use inequality as = sign
5c-20 <15c + 10
Add 20 to each side
5c< 15c + 30
Subtract 15c from each side
-10c < 30
Divide each side by -10
c < -3
(5,0) if there is no y then it is a 0
{ x + 4y = 22 ( + x - x = 0 )
{ - x + 5y = 23
4y + 5y = 22 + 23
9y = 45
y =<u> 45 </u>
9
y = 5
x + 4y = 22
x + 4 . 5 = 22
x + 20 = 22
x = 22 - 20
x = 2
S = { 2 , 5 }
When using box and arrows is called using a box plot.
