Question

Calculate the values in these expressions:
A+B+C=196. A=82, B=2C B=__? C=__?

Answer 1

B = 76, C = 38

Explanation:

A + B + C = 196

substitute A = 82 and B = 2C into the equation

82 + 2C + C = 196

82 + 3C = 196 ( subtract 82 from both sides )

3C = 114 ( divide both sides by 3 )

C = 38

B = 2C = 2 × 38 = 76
