Question

Please solve (v) with step-by-step explanation. ​

Answer 1

Answer:

x = 7/11

Step-by-step explanation:

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

[3(7x-1)] / 4 - (4x-1-x)/2 = (2x+3) / 2

(21x - 3) / 4 - (3x-1)/2 = (2x + 3) / 2

[ 21x-3 - 2(3x-1) ] / 4 = (2x + 3) / 2

(21x-3-6x+2) / 4 = (2x+3) / 2

15x - 1 = 4(2x+3) / 2

15x - 1 = 4x + 6

15x - 4x = 6 + 1

11x = 7

x = 7/11

Hope it helps you:)

Answer 2

Correct answer is:

x= 7/11

➨Step-by-step explanation:-

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

➨ [3(7x-1)] / 4 - (4x-1-x)/2 = (2x+3) / 2

➨ (21x - 3) / 4 - (3x-1)/2 = (2x + 3) / 2

➨ [ 21x-3 - 2(3x-1) ] / 4 = (2x + 3) / 2

➨ (21x-3-6x+2) / 4 = (2x+3) / 2

➨ 15x - 1 = 4(2x+3) / 2

➨ 15x - 1 = 2(2x+3)

➨ 15x - 1 = 4x + 6

➨ 15x - 4x = 6 + 1

➨ 11x = 7

x = 7/11
