    write second equation like this 4x+2y=5 then add the first equation 6x-2y=10 ____________ 10x=15

    solve for x and substitute x in one of the equation and solve for y

    Rearrange the second equation and you will get the following equations: 6x-2y=10 4x+2y=5 Solve to get: 10x=15 x=15/10=3/2 Substitute the value of x into one of the equations to get y: 4(3/2)+2y=5 6+2y=5 2y=-1 y=-1/2 Therefore, x=3/2 and y=-1/2 You can substitute these values into one or both of the equations to prove the correctness of these values.
