Question

When solving negative one over five (x − 25) = 7, what is the correct sequence of operations?

Answer 1

-$\frac{1}{5}$(x-25) = 7       multiply 5 to both sides first
-(x-25) = 35                                     then expand the brackets
-x+25=35                                        make x the subject now;
-x=10
x= -10
