Answer :
- Value of x is 3
Given :
- 5 - 7x / 2(1 +2x) = -8/7
To find :
- Value of x
Solution :
➟ 5 - 7x / 2(1 + 2x) = -8/7
➟ 7(5 - 7x) = -8[2(1+2x)]
➟ 35 - 49x = 8[2 + 4x]
➟ 35 - 49x = -16 - 32x
➟ 35 + 16 = 49x - 32x
➟ 51x = 17
➟ x = 51/17
➟ x = 3
Hence,Value of x is 3.
Verification :
➟ 35 - 49x = 8[2 + 4x]
➟ 35 - 49(3) = 8[2 + 4(3)]
➟ 35 - 147 = 8[2 + 12]
➟ 35 - 147 = -16 - 96
➟ -112 = -112
Hence , Verified
➟ 35 + 16 = 49x - 32x
➟ 35 + 16 = 49(3) - 32(3)
➟ 35 + 16 = 147 - 96
➟ 51 = 51
Hence , Verified
