Answer:

Step-by-step explanation:

(3x-4)+(3x+16)=180

3x-4+3x+16=180

3x+3x-4+16=180

9x+12=180

x+12=180/9

x+12=20

x=20-12

x=8

Answer 2

Answer:

x = 28

Step-by-step explanation:

(3x - 4) + (3x +16) = 180

3x - 4 + 3x +16 = 180.......by opening brackets

3x + 3x -4 + 16 = 180........shuffling the terms

6x + 12 = 180

6x = 180-12.......transposing 12

6x = 168

x = 168/6.........transposing 6

x = 28
