Answer:

x =1 7/8

Step-by-step explanation:

2/3x−1/5x=x−1

Multiply by 15 to clear the fractions

15(2/3x−1/5x)=15(x−1)

10x - 3x = 15x -15

Combine like terms

7x = 15x -15

Subtract 15x from each side

7x -15x = 15x -15x -15

-8x = -15

Divide each side by -8

-8x/-8 = -15/-8

x =15/8

x = 1 7/8
