You -4x then divide 3y
y= -4/3x -7

Slope intercept form is y=mx+b so you want to subtract 4x from both sides which will now leave you with 3y=-4x-21 so now all we have to do is divide by 3 and we will get -1 1/3x-7 which is your answer

-10n+50=-7(4n+8)-2 no solution many solution

ziro4ka [17]

Answer:

n=-6

Step-by-step explanation:

distribute -7 into (4n+8)

-10n+50=-28n-56-2

combine like terms

-10n+50=-28n-58

add -28n on both sides

-10n+28n+50=-58

combine like terms again

18n+50=-58

subtract 50 on both sides

18n=-108

divide both sides by 18

$\frac{18x}{18} =\frac{-108}{18}$

x=-6

hope this helps

#14 write the given sentence as an equation. Tim'S age in 7 years will be three times what it was 19 years ago

kobusy [5.1K]

The first thing we must do for this case is to define variables.
We have then:
x = Tim's age
Now we write the equation:
x + 7 = 3 (x-19)
Answer:
Tim's age in 7 years will be three times what it was 19 years ago:
x + 7 = 3 (x-19)
