Before adding or subtracting any fraction the denominator (bottom number) needs to be the same. To get the common denominator, multiply the first fraction by 2 and the next two fractions by 9.
After getting to a common denominator the bottom of the fraction does not need to be copied, because the equation has the same value without it:
2(x+7)-27=9(x-3) after expanding the brackets the equation becomes:
All terms containing x will be moved on one side of the “=” sign and the rest of the terms need to be moved on the other side on the “=” sign.
