ANSWER:

The value of

  • a = 3/8
  • c = 3/8
  • d = 1/8
  • e = 1/2

GIVEN:

  • a = c

  • b = 2e

  • b = 2c + 2d

  • 3b = 6C + 2d + e

  • b = 1

TO FIND:

  • The value of a, c, d, e.

EXPLANATION:

b = 2e

Substitute b = 1

1 = 2e

e = 1 / 2

3b = 6c + 2d + e

Substitute b = 1 and e = 1 / 2

3(1) = 6c + 2d + 1/2

3 - 1/2 = 6c + 2d

Multiply by 2 on both sides.

6 - 1 = 12c + 4d

12c + 4d = 5 -------> 1

b = 2c + 2d

Substitute b = 1

1 = 2c + 2d

Multiply by 2 on both sides.

4C + 4d = 2 -------> 2

Subtract equation 1 by equation 2

12c - 4c + 4d - 4d = 5 - 2

8c = 3

c = 3/8

Substitute c = 3/8 in equation 2

4(3/8) + 4d = 2

3/2 + 4d = 2

4d = 2 - 3/2

4d = (4 - 3) / 2

4d = 1/2

d = 1/8

c = a = 3/8

VERIFICATION:

3b = 6c + 2d + e

Substitute c = 3/8 , d = 1/8, e = 1/2 and b = 1

3(1) = 6(3/8) + 2(1/8) + 1/2

3 = 3(3/4) + (1/4) + 1/2

3 = (9/4) + (1/4) + 1/2

3 = (9 + 1 + 2) / 4

3 = 12/4

3 = 3

HENCE VERIFIED.
