Answer: 1. F: 63° 2. B: 138° 3. C: 117° 4. A: 114°

Explanation:

1.

8x-49=2x+35

8x-49+49=2x+35+49

8x=2x+84

8x-2x=2x+84-2x

6x=84

Divide both parts of the equation by 6:

x=14

Hence,

2(14)+35=

28+35=

63° (F)

2.

10x-18+15x+48=180

25x+30=180

25x+30-30=180-30

25x=150

Divide both parts of the equation by 25:

x=6

Hence,

15(6)+48=

90+48=

138° (B)

3.

7x+5=12x-75

7x+5-7x=12x-75-7x

5=5x-75

5+75=5x-75+75

80=5x

Divide both parts of the equation by 5:

16=x

Hence,

7(16)+5=

112+5=

117° (C)

4.

27x-21+10x+16=180

37x-5=180

37x-5+5=180+5

37x=185

Divide both parts of the equation by 37:

x=5

Hence,

27(5)-21=

135-21=

114° (A)
