Question 796128
8-2x=30    Since 8  does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 8  from both sides. 

−2x=−8+30 

 Add 30  to −8  to get 22. 

−2x=22 

 Divide each term in the equation by −2. 

−2x −2  =22 −2   

 Move the minus sign from the denominator to the front of the expression. 

2x 2  =22 −2   

 Cancel the common factor of 2  the expression 2x 2  . 

 1   2   x   2     =22 −2   

 Reduce the expression 2x 2    by removing a factor of 2  from the numerator and denominator. 

x=22 −2   

 Move the minus sign from the denominator to the front of the expression. 

x=−22 2   

 Cancel the common factor of 2  the expression −22 2  . 

x=− 11   22      2      

 Reduce the expression −22 2    by removing a factor of 2  from the numerator and denominator. 

x=−11
