Question

U=9i-9j and v=-8i 4j find u-v

Answer 1

u - v = 17i -13j

Explanation:

Rewrite u=9i-9j and v=-8i 4j vertically:

u=9i-9j

v=-8i + 4j

We want to subtract the second equation from the first:

u=9i-9j

v=-8i + 4j

-----------

u - v = 17i -13j

Note: I assumed that a " + " sign precedes 4j in the second equation.
