7 0

Answer:

a = 0

Step-by-step explanation:

3(4a+7)=5(2a+4)+1 Distribute 3 through the parentheses

- > 12a + 21 = 5(2a + 4) +1

5(2a + 4) +1 --> 10a + 20 + 1

12a + 21 = 10a + 20 + 1 --> 12a + 21 = 10a + 21 --> 12a = 10a

12a - 10a = 0 --> 2a = 0

Divide both sides of the equation by 2 --> a = 0
