Well, first you'd have to get the x by it's self.

10x+1=3x+9

Subtract 3x from each side and you'll have the x on only one side rather than two.

7x+1=9

Now I'd get rid of the 1 on the x's side. So just subtract 1 from each side.

7x=8

Then you should make it so the seven isn't there with the x either. Just divide each side by 7.

x=8/7

Each time you change something on one side, you must do the same to the other side. T find the value of a variable in an equation, simple seclude it so it's on it's own without number to make things confusing.

The answer was x=8/7 btw.

Oh! these are fun! ok so:

10x-3x=9-1

First, put the variables on one side,and the normal numbers on the other.

Keep in mind that u have to change the sign (+ or -) when you switch sides.

7x=8

Then group the numbers (10x-3x=7x)

Lastly, isolate the x, to get the

x=8/7

Hope this helps!

b. when the body converts a nutrient to another substance, there is no effect on mass balance.

Explanation:

The law of mass balance states that the mass stays the same in any chemical reaction, that is the reason why a nutrient in human body transforms to another substance like another substance, into muscles (that has mass), a body fluid ( that has mass) or another substance, but the total mass will keep the same, just in a different shape, nature or state.
