2/3х + 1/2х – ¾ = 2 – 1/3х + 2 ¼ х

Question

2/3х + 1/2х – ¾ = 2 – 1/3х + 2 ¼ х

Answer 1

2/3х + 1/2х - 3/4 = 2 - 1/3х + 2 1/4х

8/12х + 6/12х - 3/4 = 2 - 4/12х + 2 3/12х

8/12х + 6/12х + 4/12х - 2 3/12х = 2 + 3/4

18/12х - 27/12х = 2 3/4

-9/12х = 2 3/4

х = 11/4 : (-9/12)

х = 11/4 * (-12/9)

х = -33/9

х = - 3 6/9

х = - 3 2/3
