Answer 1

Step-by-step explanation:

c)   x=2a + 1

   To Prove:  3x - 2a + 4 = 4a + 7

   Solution : LHS = 3x-2a+4

 Substituting the value of x ,

                    LHS = 3(2a + 1) - 2a +4

                            = 6a + 3 - 2a + 4

                            = 4a +7

Hence Proved

d)  a=3b=2c

    3b=2c

   b=2c/3

    a=3b=3(4/3) = 4

   a+6b+c = 4+6(2c/3) + c

   Substituting the value of c=2

   a+6b+c = 4 +6(2*2/3) + 2

                = 4 + (4*2) + 2

                = 4 + 8 + 2

                = 14
