How do you do 25x equals 10-5x?

Answer 1

25x=10-5x

You would need to add 5x to each side to get the variables on the same side. You would add it because addition is the opposite of subtraction.

25x=10-5x

+5x +5x

----------------

30x=10

Then you would divide 30 on each side to find the value of x. You would divide it because 30x is 30 times x, and division is the opposite of multiplication. You need the opposite to cancel out what you need to get rid of-- in this case, it's the 30.

30x=10

--- ---

30 30

Now we have x=10/30.

You can reduce this fraction to 1/3 by dividing both sides by 10, the common factor in both numbers.

x=1/3 is the final answer!
