Interpreting B as b, substitute b = 2a − 23 into 4a + 3b = 1:
4a + 3(2a − 23) = 1
4a + 6a − 69 = 1
10a − 69 = 1
10a = 70
a = 7
Then b = 2(7) − 23 = 14 − 23 = −9.
Solution: a = 7, b = −9 (check: 4·7 + 3·(−9) = 28 − 27 = 1).
4a + 3(2a − 23) = 1
4a + 6a − 69 = 1
10a − 69 = 1
10a = 70
a = 7
Then b = 2(7) − 23 = 14 − 23 = −9.
Solution: a = 7, b = −9 (check: 4·7 + 3·(−9) = 28 − 27 = 1).
