Here we have the equation:
[tex]3x+7=11x+15[/tex]
To solve the equation, we need to pass all the "x terms" to a side of the equation together and all the numbers to the other side. Notice that always that any term changes to the other side of the equation, its sign is going to change too.
This is:
Now, when a number is multiplying "x", we pass it to the other side to divide the number in the other side. This is:
