Answer:
5(a-2) + (a-3) = 2(2a + 1) - 9
5a - 10 + a - 3 = 4a + 2 - 9
5a + a - 10 - 3 = 4a - 7
6a -13 = 4a - 7
6a - 4a = 13 - 7
2a = 6
a = 6/2
a = 3

Answer:
3
Step-by-step explanation:
5 ( a - 2 ) + ( a - 3 ) = 2 ( 2a + 1 ) - 9
5a - 10 + a - 3 = 4a + 2 - 9
5a + a - 10 - 3 = 4a - 7
6a - 13 = 4a - 7
6a - 4a = - 7 + 13
2a = 6
a = 6 / 2
a = 3
