Answer:

Step-by-step explanation:

First, arrange this word problem as an equation. Using N as the unknown number, we see:

(N/-5) + (-2) = -4

Next, we add -2 to both sides of the equation:

(N/-5) = -2

Now multiply both sides by -5:

N=10

Hope that helps!

3/4(x + 3) = 9 How do I solve this

Sonbull [250]

Answer:

x = 10

Step-by-step explanation:

so first distribute the 3/4 to everything on the inside

3/4x + 1 1/2 = 9

now subtract 1 1/2 on both sides

3/4x = 7 1/2

Now divide both sides by 3/4

x = 7 1/2 divided by 3/4

x = 15/2 divided by 3/4

x = 15/2 times 4/3

x = 5/1 times 2/1

x = 10
