Question 265056
2(x-1)+5x=23
           Take the 2 and multiply it by the x and -1 in the parenthesis
 
2x-2+5x=23 Now add the like terms together; the x's

2x+5x=7x

7x-2=23    Take the 2 and add it to the other side of the equation
     
7x  =25    Now take 7 and divide it by both sides so you get x by itself

x=25/7
