Question

I need help answering this question:
-3(4x + 3) + 4(6x + 1) = 43

Answer 1

What do you get when you distribute

Answer 2

-3(4x + 3) + 4(6x + 1) = 43
-12x + -9 + 24x + 4 = 43
-12x + -5 + 24x = 43
12x + -5 = 43
12x = 38
x = 3?

Answer 3

You made a mistake on the 2nd to last line, it should be 12x = 48

Answer 4

oh my god I make the stupidest mistakes.... thank you!

Answer 5

no worries, for the most part, you know exactly what you're doing...very nice work

Answer 6

i notice i often miss minimal steps in equations and problems, even though i know what i'm doing i'll miss an important part and throw off my entire answer. is there a way i can work on that?

Answer 7

or a minimal part, not even an important part, it throws off the entire thing though

Answer 8

just be very careful and make sure to check your work

you can do the check like so

-3(4x + 3) + 4(6x + 1) = 43

-3(4(4) + 3) + 4(6(4) + 1) = 43 ... Plug in x = 4

-3(16 + 3) + 4(24 + 1) = 43

-3(19) + 4(25) = 43

-57 + 100 = 43

43 = 43

So the equation is true, which verifies the answer

Answer 9

You can also graph to make sure things are equivalent, but a simple check should do

Answer 10

alright, will work on! thank you again!

Answer 11

you're welcome
