<u>HOW CAN HE CHECK HIS ANSWER:</u>
HE CAN CHECK HIS ANSWER BY PLUGGING IN HIS X VALUE, AFTER HE GETS THE CORRECT ANSWER.
<u>SHOW THE CORRECT ANSWER:
</u> <span>3(3x+6) = 4(7x-1)
9x+18 = 28x-4
18 = 19x-4
22 = 19x
22/19 = x
</span><u>
CHECK:
</u><span>3(22/19+6)/8 = 7(22/19-1)/6
45/38 = 45/38 ( Is true)</span><u>
hope this helps!!</u>
