Question

2/7(x-9)+X/3=3 solve​

Answer 1

Answer:

X = 9

Step-by-step explanation:

2/7(x-9) + x/3 = 3

(2x - 18)/7 + x/3 = 3

6x - 54 + 7x /21 = 3

(13x - 54) / 21 = 3

13x - 54 = 3*21

13x - 54 = 63

13x = 63 + 54

13x = 117

x = 117/13

x = 9

Verification:-

LHS :-

2/7(9-9) + 9/3 = 3

2(0)/7 + 3 = 3

0/7 + 3 = 3

0 + 3 = 3

3 = 3

So, LHS = RHS
