    @breanna1999 does this follow the same rule like the other one?

    You must first change the < sign to an equal sign so you can solve the problem

    The right side of the problem has your terms that you must combine and the left side a single term all by itself. This problem is asking you to solve it so you will have 38<4x+3+7-3x becomes 38=4x+3+7-3x

    why just say x when it's x1 ?

    1x is equal to x because there is an imaginary 1 in front of the x

    if it was 2x 3x 4x 5x 6x it will still equal x?

    My teacher always taught me that if you have 1x you can just leave it as x because of the understood 1 in front of it

    so even if it was 2x and up ? it will still be as x. or is it just the number 1x = x

    You solved by combining like terms for the first one for the second one you have a two step equation

    38=x+10 is correct now we have to solve the equation. Do you know how to do this?

    This question is askin you to solve to find the inequality. You must have x on one side by itself. In order to do this you must subtract 10 from both sides

    so subtract 10 from 38 and 10?

    Yes 10-10 equals 0 and 38-10 equals 28
