    R = 4 x + 8y [ Given ]

    when,

    x = 4 and R = 32

    ★ Substituting the values

    => 32 = 4 * 4 + 8y

    => 32 = 16 + 8y

    => 8y = 32 - 16

    => 8y = 16

    => y = 8/16

    => y = 2

    Step-by-step explanation:

    R=4x+8y

    (substitute given values)

    32=4*4+8y

    32=16+8y

    32-16=8y

    16/8=y

    2=y

    hence answer is 2
