First you need to get x on one side of the equation and to do that subtract 2a from both sides.
28 + 2a = 5a + 7
-2a -2a
28=3a+7
Then we need to get a alone by subtracting 7 on both sides.
28=3a+7
-7 -7
21=3a
Finally divide each side by 3 and you should get a = 7. Hope this helps!
For this case we have the following fractions:

We must rewrite the fractions, using the same denominator.
We have then:
We multiply the first fraction by 11 in the numerator and denominator:

We multiply the second fraction by 2 in the numerator and denominator:

Rewriting we have:
For the first fraction:

For the second fraction:

We note that:

Answer:
The fractions are not equivalent:

The answer is 2/52 or if you want a rounded up answer it is 1/26
Answer:
yes.
