    Answer:

    Step-by-step explanation:

    5 x + 10 y = 15  (1)

    10 x + 3 y = 13

    We want to use the linear combination method and addition to eliminate the x-terms, so we want in the equation  (1), there will be the term -10x. Then, we have to multiple both side of (1) by -2.

    And we have

    -10 x – 20 y = – 30

    10 x + 3 y = 13

    ——————- (add)

    0 – 17y = -17

    or y = 1 and x = 1
