Question

2/3a,3/5a,-6/5a. Please solve

Answer 1

Answer :

• The answer is not clear as the sign are not there.
• Most probably I think there should be plus sign.

= $\dfrac{2}{3a} + \dfrac{2}{3a} +( \dfrac{-6}{5a})$ = 0

= $\dfrac{10 + 10 + (- 18 )}{15a}$ = 0

= $\dfrac{20 + (- 18 )}{15a}$ = 0

= $\dfrac{20 - 18 }{15a}$ = 0

= $\dfrac{2}{15a}$ = 0

= a = $\dfrac{15}{2}$

= a = 7.5

Answer 2

Answer:

Answer is a upon 15 or a/15

Step-by-step explanation:

Explanation: 2/3a+3/5a+(-6/5a)

= 2/3a+3/5a-6/5a

= a[ 2/3+3/5-6/5]

= a[ 2/3-3/5]

= a [ 10-9/15]

= a×1/15

= a upon 15 or a/15
