7x + 12 = 13x
to solve this equation for x you must get all the x's together.
,
subtract 7x from both sides.
12 = 13x - 7x
combining like terms.
12 = 6x
,
we are still trying to get the x by it's self so we must get rid of the 6. the 6 is multiplied by to the x so to get rid of it we must divide.
,
divide both sides by 6.
12/6 = (6x)/6
2 = x
the solution to the equation is x = 2
,
to check this you can plug x = 2 into the original equation to see if it is true.
,
7(2) + 12 = 13(2) ?
14 + 12 = 26
26 = 26
this is true so we solved the equation correctly! :)

How do you do 24 equals 7x plus 5x?
The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.
6x plus 10 plus 7x equals -146?
