Answer 1

Answer:

$5(3x + 4) - 8(6)( - 7) = 9x - 8 \\ \\ 15x + 20 -336 = 9x - 8 \\ \\ 15x + 316 = 9x - 8 \\ \\ 15x - 9x = - 8 - 316 \\ \\ 6x = - 324 \\ \\ x = \frac{324}{6}$

Answer 2

Answer :

5(3x+4) - 8(6-7) = 9×-8

15x + 20 - 48 + 56 = -72

15x = -72-56+48-20

15x = 60

x = 60÷15= 4

Therefore x= 4

Hope this helps...
