π˜‚ = 5𝗢 βˆ’ 𝗷, π˜ƒ = βˆ’2𝗢 + 𝗷
a) u+v
b) u-v
c) 2u βˆ’ 3v
d) 1/2v + 4u

  1. Just do the simple arithmetic.
    I will do c)

    2u - 3v
    = 2(5𝗢 βˆ’ 𝗷) - 3(βˆ’2𝗢 + 𝗷)
    = 10i - 2j + 6i - 3j
    = 16i - 5j

    I will assume you know how to sketch that resultant vector. (16 to the right, 5 down)
