-4w=-39/3-5/3
-4w=-44/3

alexandervonhumboldt2 · Answer

w=44/3*1/4

alexandervonhumboldt2 · Answer

w=11/3

campbell_st · Answer

is the question 

1. $$\frac{-4w + 5}{3} = -13$$

or 

2. 

$$-4w + \frac{5}{3} = -13$$

.1

campbell_st · Answer

ok.... multiply both sides of the equation by 3, with remove the denominator

so 

-4w + 5 = -39

does that make sense..?

anonymous · Answer

yes, thanks.

campbell_st · Answer

can you solve it from here, or do you need further help..?

campbell_st · Answer

Oh, and the answer isn't the one that has been posted

anonymous · Answer

I know, and yeah, i still need help haha

campbell_st · Answer

ok... so next subtract 5 from both sides of the equation. What do you get..?

anonymous · Answer

-1w = -34 ....?

campbell_st · Answer

no 

-4w + 5 = -39
        -5      -5  
--------------
 -4w     = -44

last step is divide both sides by -4

anonymous · Answer

ohhhh 11

i was overthinking it! Thanks @campbell_st

campbell_st · Answer

here is an alternate method called backtracking .... it uses a road map

read the equation

start with w

multiply it by -4 

then add 5

divide everything by 3 

it all equations -13 '
