how do i figure this out step by step?
Start out by writing out the equation again.
Bring all variables and constants to either sides of the equation.
Finally, solve for x.
The goal of the problem is to get the x by itself and figure out what x is. The first thing you should do is work with the whole numbers 7 and 13.
add 7 to both sides. By adding 7 to both sides you are not changing the equation but equaling it out. the new equation should be
Now subtract 5x from each side
your new equation should be
divide each side by -2
