    -3/x+2 * 5x+10/9

    ax+am+3x+3m/a^2-9 / 2x+2m/a-3

    solve and write the answer in the lowest term:
    5a^2b/12a * 2a^3b/15ab^6

    solve the equation
    x/x-1-3/x=1/2

    solve for y:
    2(b+y)=b

    solve by substitution
    y=3x+11

    2x+3y=0

    x+2y=1

    8x+6y=4

    solve by addition
    -3x+y=3

    2x-3y=5

    solve by addition:
    x+3(y-1)=11

    2(x-y)+8y=28

    solve for 3 variables:
    2x-y+z=5

    x+y-2z=-4

    3x-y+3z=10

    Perform operation and simplify
    5/root2

    root 15/2+root5

    find all real solutions:

    W^2=100

    Find all real solutions
    3^ root 2x+9=3

    root x-3=(root x+2)-1

    solve using quadratic formula:
    2x^2+5x-3=0

    solve by completing the square:

    x^2+10x+25=0

    solve by using the quadratic formula:
    x^2+6x+6=0

    solve by method:
    x(x+1)=12

    a^4-5a^2+4=0
