Noah wanted to check his solution of x = 14/5 for the equation 1/2 ( 7x - 6 ) = 6x - 10 substituting 14/5 for x , he writes the following:
1/2 ( 7 ( 14/5 ) - 6 ) = 6 ( 14/5 ) - 10
( 7 ( 14/5 ) - 6 ) = 12 ( 14/5 ) - 20
5 ( 7 ( 14/5 ) - 6 ) = 5 ( 12 ( 14/5 ) - 20 )
7 ⋅ 14 - 6 = 12 ⋅ 14 - 20
98 - 6 = 168 - 20
92 = 148
Find the incorrect step in Noah's work and explain why it is incorrect.
