5x - 9 = 3(4x - 3) - 7x is this right?

OpenStudy (anonymous):

No

OpenStudy (jack1):

OpenStudy (anonymous):

\[3(4x -3) -7 = 5x - 9\]

OpenStudy (jack1):

OpenStudy (jack1):

cool, so first, expand out the brackets \(\large 3(4x -3) -7x = 5x - 9\) \(\large 3 \times 4x - 3 \times 3 -7x = 5x - 9\) \(\large 12x - 9 -7x = 5x - 9\) \(\large 5x - 9 = 5x - 9\) k, can u see the answer yet?

OpenStudy (anonymous):
