    2x+6y = 10

    3x+9y = 15

    Step-by-step explanation:

    We can multiply the equation by 2

    2 (x + 3y) = 5*2

    2x+6y = 10

    Or we can multiply by 3

    3 (x + 3y) = 5*3

    3x+9y = 15

    Multiplying each side by the same number gives us an equivalent equation

    Standard form is

    Ax + By = C

    Which the equation is already written in

    1) 2x + 6y = 10

    2) 4x + 12y = 20

    Step-by-step explanation:

    x + 3y = 5

    Every scalar multiple of this equation will be its equivalent

    1) 2x + 6y = 10

    2) 4x + 12y = 20
