Question

solve the following equation
9(49a+7)=5(8a+3)​

Answer 1

Answer:

9(49a+7)=5(8a+3)

441a+63=40a+15

441a-40a=15-63

401a=-48

a=-48/401

a=0.119700

Answer 2

Answer:

$9(49a + 7) = 5(8a + 3) \\ 441a + 63 = 40a + 15 \\ 441a - 40a = 15 - 63 \\ 401a = - 48 \\ \boxed{a = \underline{ \underline{ \frac{ - 48}{401} }}}$
