    Answer:

    (-3.1, -32.5)

    Step-by-step explanation:

    Set the equations equal to each other: 25x+45=15x+14

    Solve for x: 10x = -31

    Solve for x: x=-3.1

    Plug the x value back into one of the equations to find the value of y:

    y = 15 (-3.1) +14

    y = -32.5

    Answer:

    7,68

    Step-by-step explanation:

    y=2x+54

    y=15x+14

    you can do elimination so you need to multiply the x’s by -15 and 2

    y=-30x+54

    y=30x+15

    the x’s are canceled out and you add the remaining

    y=54. y=68

    y=15

    To find x you makes an equation of one of the equations given

    68=2x+54

    14=2x

    7=x
