Question

125+{14×[40+(x+240):4]-34}×17=47147

Answer 1

125+{14×[40+(x+240):4]-34}×17=47147

{14×[40+(x+240):4]-34}×17=47147-125

{14×[40+(x+240):4]-34}×17=47022

14×[40+(x+240):4]-34 = 47022:17

14×[40+(x+240):4]-34 = 2766

14×[40+(x+240):4] = 2766+34

14×[40+(x+240):4] = 2800

40+(x+240):4 = 2800:14

40+(x+240):4 = 200

(x+240):4 = 200-40

(x+240):4 = 160

x + 240 = 160 × 4

x + 240 = 640

x = 640 - 240

x = 400
