    Moments

    Suppose that the reactions at A and B are R_A and R_B respectively. Then, take moments about A:

    M(A):14 \times 3 + 50 = R_B \times 10

    \Rightarrow R_B = \frac{92}{10} = 9.2

    M(B): R_A \times 10 + 50 = 14\times 7

    \Rightarrow R_A = \frac{48}{10} = 4.8

    You can check by resolving vertically that R_A+R_B = 14
