solve the systems of equations

{4/7x+y=2/7
-1/8x-3/4y=-11/4

a. the solution of the system is
b. there are infinitely many solutions
c. there is no solution

  • algebra -

    Multiply both sides of first equation by 7.

    4x + 7y = 2

    Multiply both sides of second equation by 8.

    -x - 6y = -22

    To get x terms equal, multiply both sides by 4.

    -4x - 24y = -88

    Add first and third equation.

    -17y = -86

    Solve for y and then for x.
