Question

Does anyone know the answer to this?

Answer 1

first you have

65 (3x-10) 2x =18O
65 + 5x-10 180
55 5x -180
5x 125 x 125/5 25 X 25

B 3 (25) -10 75-10 65

C 2 (25) 50

it this is

Answer 2

65 + (3x-10) + 2x = 180

65 +5x-10 = 180

55 + 5x =180

5x = 125

x = 125/5 = 25

x = 25

B = 3(25)-10 = 75-10 = 65

C = 2(25) = 50
