Question

how do i figure this out step by step?
3x-7=5x+13

Answer 1

Start out by writing out the equation again.

3x-7=5x+13

Bring all variables and constants to either sides of the equation.

3x-7=5x+13
-2x=20

Finally, solve for x.

-2x=20
x=-10

Answer 2

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.
3x-7=5x+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
3x=5x+20
Now subtract 5x from each side
your new equation should be
-2x=20
divide each side by -2
-2x/-2=20/-2
x= -10
