3x+5=2x+9
This is quite a simple question.
Move the numbers so x's are on one side and so the numbers are on one side. Remember, when you move something over the = sign, the positive/negative sign changes to the opposite.
Move the 2x over so it becomes 3x-2x+5=9
Move the 5 over so it becomes 3x-2x=9-5
Solve the equation so far
1x=4
Divide the number by the number before the x
4/1=4
x = 4
I hope this helped
