    Answer:

    (4,11)

    Step-by-step explanation:

    y=2x+3

    y=5x-9

    the first equation is equal to the second equation so

    2x+3=5x-9

    put like terms together

    2x-5x= -9-3

    -3x= -12

    divide both sides by -3

    .•.x=4

    now, use the value of x to find the value of y like this:

    y=2x+3 (x=4)

    y=2(4)+3

    y=8+3

    y=11

    therefore, the two lines intersect at the point (4,11)
