Graph the system of inequalities y> 2x-3 and 3y-x≤6
Veronika [31]
Y > 2x - 3
3y - x ≤ 6
       ↓
y = 2x - 3
3y - x = 6

    3(2x - 3) - x = 6
3(2x) - 3(3) - x = 6
        6x - 9 - x = 6
        6x - x - 9 = 6
             5x - 9 = 6
             <u>    + 9 + 9</u>
                  <u>5x</u> = <u>15</u>
                   5      5
                    x = 3
y = 2x - 3
y = 2(3) - 3
y = 6 - 3
y = 3
(x, y) = (3, 3)

X = 4(180 - x)
x = 720 - 4x
4x + x = 720
5x = 720
x = 720/5
x = 144

180 - x =
180 - 144 =
36

the measure of the angle is 144...the measure of its supplement is 36
