1) 17-x = 41

17-x + x =41+x = 17-41= 41-41+x= x= -24 Is this correct?

2) -(6-3)^5

-(3)^5 = -(3^5) = -243 Is this corrrect?

3)14-3^5 ÷ 3x3^3

14-243 ÷ 3x27

14-81x27=

14-2187= -2173 Is this correct?

Thanks

Try using the pre tags to enclose and line up your work more neatly.

1)

17-x = 41

-17 -17 <-- subtract 17 from both sides of equation

-x = 24 <-- leaves you with this

*(-1) *(-1) <-- convert x to positive by multiplying each by -1

x = -24

17-(-24) = 41 ?? <-- check answer ...true??

Your other two answers look correct to me.
