5x+6y=37
2x-3y=-4

  • maths - ,

    what are we doing?
    solving?

    keep the first as is: 5x+6y=37
    double the second: 4x - 6y = -8
    add them
    9x = 29
    x = 29/9

    in the 1st:
    5(29/9) + 6y = 37
    times 9
    145 + 54y = 333
    54y = 188
    y = 188/54 = 94/27

    x = 29/9 , y = 94/27
