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]
