Answer:

x = -4

Explanation:

( -17 ) × { ( -5 ) + x } = ( -17 ) × ( -5 ) - ( -17 ) × 4

85 - 17x = 17 × 5 + 17 × 4

85 - 17x = 17 × ( 5 + 4 ) (TOOK 17 AS COMMON)

85 - 17x = 17 × 9

85 - 17x = 153

-17x = 153 - 85

-17x = 68

x = 68 / (-17)

x = - 4 ( Ans )

Verified answer

Explanation:

(-17) × [(-5) + x] = (-17) × (-5) - (-17) × 4

85 + (-17x) = 85 -(-68)

85 + (-17x) = 153

-17x = 153 - 85

x = 68/(-17)

x= -4
