x = 2
Explanation:
First, make sure they both have common denominators ( 15 )
5 × 3 = 15 and 3 × 5 = 15
Whatever you do to the denominator you have to apply to the numerator. So, multiply the numerator and denominator of the first fraction by 3.
=
Next, multiply the numerator and denominator of the second fraction by 5.
=
Now we have:
Use distributive property on the numerators of both fractions.
Since the denominators are equal we can ignore them for now and find x.
9x - 3 = 5x + 5
We need to move like terms to different sides to isolate x. First, we can subtract 5x from both sides.
9x - 5x - 3 = 5x - 5x +5
4x - 3 = 5
Then, we can add 3 to both sides to cancel out the -3.
4x - 3 + 3 = 5 + 3
4x = 8
Finally, to find x we divide both sides by 4.
4x ÷ 4 = 8 ÷ 4
x = 2
