Question

6+х=13 13-х=5 х+7=12

Answer 1

6+х=13 13-х=5 х+7=12

х=13-6 х=13-5 х=12-7

х=7 х=8 х=5

Answer 2

To solve each of these equations for the variable x, follow these steps:

1. 6 + x = 13: Subtract 6 from both sides to isolate x. x = 13 - 6 x = 7

2. 13 - x = 5: Subtract 5 from both sides to isolate x. -x = 5 - 13 -x = -8

   Note: To get x alone on one side, multiply both sides by -1 (since -1 * -x = x). x = -1 * (-8) x = 8

3. x + 7 = 12: Subtract 7 from both sides to isolate x. x = 12 - 7
