answer:
= 343/15972
step by step explanation:
LHS
= 7/11 × 4x × 11/7 × 3x
so,here 7/11 will get cancel due to division.....
= 4x × 3x = 12x
so LHS will be 12x
and RHS will be 343/1331
12x = 343/1331
hence by equating we get
x = 343/1331 ÷ 12
x = 343/1331 × 1/12
so, x = 343×1 ÷ 1331×12
hence value of x becomes
that is, x = 343/15972
