Let's solve each equation separately:
1) 70 - (6x - 40) = 2070 - 6x + 40 = 20110 - 6x = 20-6x = -90x = 15
2) (320/x + 8) / 6 = 8320/x + 8 = 48320/x = 40x = 8
Therefore, the solutions are x = 15 and x = 8.
Let's solve each equation separately:
1) 70 - (6x - 40) = 20
70 - 6x + 40 = 20
110 - 6x = 20
-6x = -90
x = 15
2) (320/x + 8) / 6 = 8
320/x + 8 = 48
320/x = 40
x = 8
Therefore, the solutions are x = 15 and x = 8.
