Answer 1

Answer: Solve it like this



Step-by-step explanation: X2+ 62 = 102

                                              X2 = 102- 62

                                        X2 = 40

                                        X2/2 = 40/2

                                       X = 20

Answer 2

2x = 102 - 62

x = 40/2

x = 20
