Respuesta :

4(3A - 4) = 56
first distribute 4
12A - 16 = 56
then add 16
12A = 72
finally, divide by 12
A = 6

Answer:

A = 6

Step-by-step explanation:

First, use the distributive property on the left side:

[tex]4(3A - 4) =56\\12A - 16 = 56[/tex]

Add 16 to both sides

[tex]12A = 72[/tex]

divide both sides by 12

[tex]A = 6[/tex]
