Question

2x+1/3 + 4x+1/2 - 3x+5/5 = 9/10

Answer 1

Answer:

x = 227 / 90

Step-by-step explanation:

Question: 4x + 1/3 + 2x - 1/2 - 3x - 7/5 = 6

To find the value of 'x'.

Taking LCM we get,

⇒ ( 4x + 1/3 ) + ( 2x - 1/2 ) - ( 3x - 7/5 ) = 6

⇒ ( 12x + 1 ) / 3 + ( 4x - 1 ) / 2 - ( 15x - 7 ) / 5 = 6

LCM is 30, hence we get,

⇒ ( 120x + 10 + 60x - 15 - 90x - 42 ) / 30 = 6

⇒ ( 90x - 47 ) = 30 × 6

⇒ 90x = 180 + 47

⇒ 90x = 227

⇒ x = 227 / 90
