Solve for y, then find the value of y when given x = –2.
6x = 7 – 4y

Question

jamesj · Answer

When x = -2

6x = -12

So 12 = 7 - 4y

hence ... can you take it from here?

idk i was doing this problem and i got that far and i messed it up i think. it came out like 10-y and i was like what? im awful at math. ugh. :(

anonymous · Answer

To solve for y, subtract 7 from both sides and then divide both sides by -4.

$$y = (-6x + 7) \div 4$$

then just plug in x value
when x = -2:

$$y = [-6(-2) +7] \div 4 $$
y(-2) = 4.75

oops i forgot a negative?

anonymous · Answer

wait but the options are -12, 7 fourths, 19 fourths, and 24.

anonymous · Answer

y = 19/4  = 4.75 

I didn't know it was multiple choice, I just put it into decimal form
