Answer:

x= -1/2 and -32

y = -10

Step-by-step explanation:

1) 2(-4x-8y)= (-48)2

8x+3y =-34

*to create a way to cancel out the x*

2) -8x-16y= -96

8x+3y= -34

*add them

-8x +8x =0

-16y + 3y = -13y

-96+ -34= -130

3) -13y =-130

isolate y

4) y = -10

*plug in* to find x into both original equations*

5) 8x + 3(-10) = -34. -4x-8(-10)= -48

*follow order of operations to solve for x

6) 8x -30 =-34. -4x +80 = -48

7) 8x =-4. -4x =128

8) x= -1/2. x = -32

Answer:

<h3>           m∠BAC = 80° </h3>

Step-by-step explanation:

m∠BCD = 145°  ⇒  m∠BCA = 180° - 145° = 35°

From ΔABC:

                    m∠ABC + m∠BCA + m∠BAC = 180°

                         65° +  35° + m∠BAC = 180°

                                  m∠BAC = 180° -  100°

                                   m∠BAC = 80°
