3 over a+2 over 3a =11 over 15
Answered by Bosnian
If your expression mean :

3 / a + 2 / 3 a = 11 / 15

Then :

3 * 3 / ( 3 * a ) + 2 / 3 a = 11 / 15

9 / 3 a + 2 / 3 a = 11 / 15

11 / 3 a = 11 / 15 Multiply both sides by 3a

11 * 3 a / 3 a = 11 * 3 a / 15

11 = 33 a / 15 Multiply both sides by 15

11 * 15 = 33 a

165 = 33 a Divide both sides by 33

165 / 33 = 33 a / 33

5 = a

a = 5
