multiply by 4
subtract 17
change the sign

anonymous · Answer

$$\LARGE \frac{17-x}{4}=-10$$

use cross multiplication  ... and you'll have...  17-x=-40

then move 17 to the right side and you'll have...

-x=-41-17

-x=-58

multiply by -1 both sides and you have..

x=58

anonymous · Answer

Multiply both side by 4
(17-x)=-10(4)
17-x = -40
Subtract 17 from both side
-x = -57
Multiply both side by -1
x = 57
