    Given equations are:

    m PQR = x + 7,

    m SQR = x + 3,

    and m PQR + m SQR = m PQS = 100

    using those equations we need to find value of x.

    Plug value of (m PQR = x + 7) and (m SQR = x + 3) into (m PQR + m SQR = m PQS = 100)

    (x+7) + (x+3) = m PQS = 100

    (x+7) + (x+3) = 100

    Remove parenthesis

    x+7 + x+3 = 100

    Rearrange terms

    x + x + 3+7 = 100

    Combine like terms

    2x+10 = 100

    2x = 100 - 10

    2x=90

    x=90/2

    x=45

    Hence final answer is x = 45.
