    x = 7 + 4y so insert 7 + 4y for x in the second equation 5x + 9y = 6

    It must have been included in the question. They wouldn't have said "using the elimination method:" without including a specific elimination method

    You should try to figure it out yourself. Don't just ask for the answer.
