Answer:

add the variable to the one that is in the other side

Explanation:

Example:

2x-3=5x+3

2x+5x= 7x

so

7x-3=+3

now add negative 3 to 3

-3+3=0

so

7x=0

7×/7= 0/7

x=0

Answer:

If it's the same variable, cancel the variable on one side.

Explanation:

Ex: 2x -10= 3x +15

-10= x +15

-25= x

x= -25
