solve for x

5x= -7

divide the left hand side and the right hand side by the ceofficient of x which is 5......

5x/5= -7/5

answer..... x=-7/5

5x=-7  becomes _5x_=_-7_      

                             5        5

 then cross out the 5s on the left of the equation which leaves you with X= _-7 _

                                                                                                                        5

 

X equals -7 divided by 5 

        X=1.4       because negative 7 divided by 5 equals 1.4
