To solve these equations:
1) Х + 460 = 660
Subtract 460 from both sides:
Х = 660 - 460Х = 200
2) Х - 380 = 240
Add 380 to both sides:
Х = 240 + 380Х = 620
3) Х ÷ 40 = 640
Multiply both sides by 40:
Х = 640 * 40Х = 25600
Therefore, the solutions for the equations are:1) Х = 2002) Х = 6203) Х = 25600
To solve these equations:
