    Ok here we go dear ...

    There are many ways to solve this math problem in specific but i ll go for the smartest and simplest for you ...

    4x + 5y = - 2

    4x + 3y = 10

    4x = - 5y - 2

    4x = - 3y + 10

    -5y - 2 = - 3y + 10

    -12 = 2y

    -6 = y

    4x = - 3y + 10

    4x = - 3 (-6) + 10

    4x = 18 + 10 = 28

    x = 7

    y = - 6
