Question 380386: solution steps for solving (5a+7)=(6a-7) The parenthesis are not really parenthesis. They stand for absolute value signs which I don't have on the keyboard. So the equation is the absolute value of each quantity on each side of the equation. Answer by richard1234(7193) (Show Source):
You can put this solution on YOUR website! Absolute value sign |x| is typed on a keyboard using "shift"+"\"
There are two cases for this problem:
5a + 7 = 6a - 7 --> a = 14
5a + 7 = -(6a - 7) --> 5a + 7 = -6a + 7 --> a = 0
Checking, both solutions satisfy the equation.
