Start with the sum of x and 9, giving the expression
This is divided by 2 so
This equals 3x so the equation is
This can the be solved.
Multiply both sides by 2 to get
Then take x from both sides
Divide by 5 to get the value for x
This is divided by 2 so
This equals 3x so the equation is
This can the be solved.
Multiply both sides by 2 to get
Then take x from both sides
Divide by 5 to get the value for x
