Answer:

Step-by-step explanation:

6(3x – 8) = 7(7x + 7)

18x - 48 = 49x + 49

49x - 18x = - 48 - 49

31x = - 97

x = - 97/31

Answer:

x = -3.13

Step-by-step explanation:

6(3x – 8) = 7(7x + 7)

18x - 48 = 49x + 49

subtract 18x from from each side

-48 = 31x + 49

add 48 to each side

31x +97 = 0

31x = -97

divide both sides by 31

x = -3.13

check:

6(3[-3.13] - 8) = 7(7[-3.13] + 7)

-104.35 = -104.35
