Question

2a+4/7+a-3/2=3 Solve And Check Please Its Urgent ​

Answer 1

Answer:

a   =   55 / 42

Step-by-step explanation:

2a+4/7+a-3/2  =  3

2a + a - 3/2 = 3 - 4/7

2a +a           = 3 - 4/7 + 3/2

 3a              = 42/14 - 8/14 + 21/14

    3a           =  (42 -8 + 21) / 14

    3a           =    55 / 14

      a            =   55 / (14 * 3)

      a            =   55 / 42

Answer 2

Step-by-step explanation:

Given, 2a+4/7+a-3/2=3

by inter changing terms , we get

2a+a+4/7-3/2 = 3

3a + 8-21/14 = 3

14 (3a) + (8-21 )14/14 = 3(14) multiply using 14

42 a - 13 = 42

42a = 42 +13

42 a = 55

a =55/42

check : 2a+4/7+a-3/2

= 2(55/42) + 4/7 + 55/42 -3/2

= 55/21 + 4/7 + 55/42 - 3/2

= 110 +24 + 55 - 63 /42

= 189 - 63 / 42

= 126 / 42

= 3

= RHS

Hence proved

Therefore , a = 55/42
