You've come to the right place. Our Math staff had a sudden cancellation,
and at the last minute, we were able to add this problem to their schedule.
They have responded with the following solution:
4x + 9 + 3x = 30
Combine the 'x' terms on the left side of the equation:
7x + 9 = 30
Subtract 9 from each side:
7x = 21
Divide each side by 7:
x = 3
OR
4x +9+3x = 30
7x+9 = 30
7x=30-9 (Transposing 9 to RHS)
7x=21
x=21/7 (Transposing 7 to Right Hand Side)
x=3
Hence the required answer is 3.
