Christian responses to the SAB contradictions

How old was Abram when Ishmael was born?
86 years old	More than 135 years old
Genesis 16:16 And Abram was fourscore and six years old, when Hagar bare Ishmael to Abram.	Acts 7:2-4 Our father Abraham ... dwelt in Haran: and from thence, when his father was dead, he removed himself into this land. Genesis 11:26 And Terah lived seventy years, and begat Abram.... . Genesis 11:32 And the days of Terah were two hundred and five years; and Terah died in Haran.

Acts 7:4 says that Abram didn't leave Haran until after his father died. Genesis 11:26 says that Abram's father was 70 years old when Abram was born, and Abram's father lived to be 205 (11:32). Clearly, then, Abram was at least 135 when he left Haran. Yet Gen.12:4 says he left Haran when he was only 75.

How old was Abrahm when he left Haran?
