    That blank is a plus sign

    ok so rememmber you can do anythiing to an equation as long as you do it to both sides

    -0.3x+2=0.4x-0.1

    add 0.3x to both sides

    2=0.7x-0.1

    add 0.1 to both sides

    2.1=0.7x

    times 7 both sides

    21=7x

    divide both sides by 7

    3=x
