Best ResponseYou've already chosen the best response.1before you do anything, you have to get the numbers in the absolute value sign alone. In this equation, you do. So now you can just solve like a regular algebra problem. First problem will have what's NOT in the absolute value sign negative and positive. so first, you can do a problem where 7 is positive, and another problem where 7 is negative so 23x = 7 solve like a regular algebra problem 3x=9 x=3 now make 7 positive 23x=7 solve regularly 3x=5 x= 5/3
