Answer:


3a - 7

Explanation:

Greetings!!

To solve the expression first write the expression


2(2a - 5) - (a - 3)

Apply the distributive law: -(a-b) = -a+b


- (a - 3) = - a + 3


= 2(2a - 5) - a + 3

Expand by the distributive law: a(b-c) = ab-ac


2.2a - 2.5 = 4a - 10

substitute into the expression


= 4a - 10 - a + 3

Group like terms


= 4a - a - 10 + 3 \\ </p><p> = 3a - 7
