9. If f(x) = 5x-4 and f(2a) =156 , then what is the value of a?

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$f(x) = 5x - 4$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$f(2a) = 5(2a) - 4$

$f(2a) = 10a - 4$

$156 = 10a - 4$

$10a - 4 = 156$

Add sides 4

$10a - 4 + 4 = 156 + 4$

$10a = 160$

Divide sides by 10

$\frac{10a}{10} = \frac{160}{10} \\$

$a = 16$
