    8 (7) - 13=43

    R = 7

    Step-by-step explanation:

    13 less than 8R leaves 43.

    R is the unknown.

    This expression can be in an equation.

    8R-13 = 43

    Carry over the like terms. Carry over the - 13 and make R the subject.

    8R = 43+13

    8R = 56

    R = 56/8

    R = 7

    To check if the answer was correct, replace the unknown which is R with the value of what it is in brackets. Remember brackets mean to multiply.

    8 (7) - 13 = 43

    56-13 = 43

    Therefore the answer is 7
