Please help me solve this system of equations!! I keep getting no solution and i do not know what I am doing wrong.

    If you don't even know what one of the variables are, you can't solve the equasion. There IS no solution.

  • Math - ,

    First you multiply the first equation by 5 and the second equation by -2.
    You get:
    10x+25 = 80
    -10x+4y = -22
    You cancel out the 10x. Therefore you add the two equations and you get
    You plug in 2 for y in any one of the original equations and you get:
    x= 3
