<u>First Solution</u>
        -2x + y = 1
-2x + 2x + y = 1 + 2x
                 y = 1 + 2x

<u>Second Solution</u>
     -2x + y = 1
-2x + y - y = 1 - y
           <u>-2x</u> = <u>1 - y</u>
            -2       -2
              x = -0.5 + 0.5y
0.5 + x - x = -0.5 + 0.5 - x + 0.5y
           0.5 = -x + 0.5y
 -0.5y - 0.5 = -x + 0.5y - 0.5y - 0.5
   2 · (-0.5y) = 2(-x - 0.5)
                y = -2x - 1

<u>Third Solution</u>
             -2x + y = 1
        -2x + y - 1 = 1 - 1
        -2x + y - 1 = 0
-2x + 2x + y - 1 = 2x
                 y - 1 = 2x
           y - 1 + 1 = 2x + 1
                      y = 2x + 1

Find the measure of the missing angles.
Sergio039 [100]

Answer:

d = 105° , e = 32° , f = 43°

Step-by-step explanation:

d and 105° are vertically opposite angles and are congruent , then

d = 105°

e and 32° are vertically opposite angles and are congruent , then

e = 32°

105° , e and f lie on a straight line and sum to 180° , that is

105° + e + f = 180°

105° + 32° + f = 180°

137° + f = 180° ( subtract 137° from both sides )

f = 43°
