Question

1)9×-(5-×)=
2)10-4 (×-3)+5=
3)-9 (2×-1)+15×=

Answer 1

1) 9x - ( 5 -x ) =

9x -5 + x =

9x + x = 5

10 x = 5

x = 5/10

x= 1/2

2) 10 - 4 (x - 3) + 5 =

  10 -4x + 12 +5 =

-4x = -10 -12 -5

-4x = -27   (x-1)

4x = 27

x = 27/4

3) - 9 (2x - 1) + 15x =

  -18x + 9 + 15x =

-18x +15x = - 9

-3x = - 9     (x-1)

3x = 9

x= 9/3

x= 3
