subtract 3x+2 from both sides and you have
4x+2 -3x-2 = 3x+9 -3x-2
x = 7
Subtract 2 from both sides of the equation.
4x = 3x + 7
Subtract 3x from both sides
x = 7
Move 3x to the other side so it will become -3x ( 4x-3x) same with the constant number ( 9-2) . Just combine the constant and the number that has coefficient.
Solution: 4x+2= 3x+9
