To solve the equations, we can first simplify them:
1) x + 320 = 80*9x + 320 = 720x = 720 - 320x = 400
2) x - 180 = 420/6x - 180 = 70x = 70 + 180x = 250
Therefore, the solutions to the equations are x = 400 and x = 250.

x = 720 - 320
x = 400
2) x - 180 = 420/6
x - 180 = 70
x = 70 + 180
x = 250
Therefore, the solutions to the equations are x = 400 and x = 250.
