Question

como resolver 7.(×-1)-2.(×-5)=×-5

Answer 1

7(x - 1 ) - 2 (x - 5 ) = x - 5 
7 x - 7 - 2 x + 10 = x - 5
5 x + 3 = x - 5
5 x - x = -5 - 3
4 x =  - 8
x = -8/4
x = -2

Answer 2

7(x-1) - 2(x-5) = x-5

7x - 7 - 2x + 10 = x - 5

5x - 7 + 10 = x - 5

5x +  3 = x - 5

5x - x = -5 -3

4x= -8

x= -8/4

x= -2
