Question

3/4(7x-1/4)-(2x-1-x/2)=x+11​

Answer 1

Answer:

That clears all the fractions in one step. Here the LCD is 4. So if we multiply everything by 4, we get

3(7x-1) - 8x - 2(1-x) = 4x + 6

 

21x - 3 - 8x - 2 + 2x = 4x + 6

Now collect like terms and get

15x - 5 = 4x + 6

11x = 11

x = 1

Answer 2

Answer:

x = 7/9

Explanation:

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

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

(21x - 3)/4 - (5x - 1)/2 = (x + 3)/2

(21x - 3)/4 - (10x - 2)/4 = (2x + 6)/4

21x - 3 - 10x + 2 = 2x + 6

11x - 1 = 2x + 6

9x = 7

x = 7/9
