Question

Solve for n .3(n-5)=.4-.2n

Answer 1

Answer:

Answer:

n= 19 /5

Step-by-step explanation:

3(n−5)=4−2n

Step 1: Simplify both sides of the equation.

3(n−5)=4−2n

(3)(n)+(3)(−5)=4+−2n(Distribute)

3n+−15=4+−2n

3n−15=−2n+4

Step 2: Add 2n to both sides.

3n−15+2n=−2n+4+2n

5n−15=4

Step 3: Add 15 to both sides.

5n−15+15=4+15

5n=19

Step 4: Divide both sides by 5.

5n /5 = 19 /5

n= 19 /5

Answer 2

Hey there!

First, let's use the distributive property to undo the parentheses.

0.3n-1.5=0.4-0.2n

First, we want to put all the variables on the left. So, we will add 0.2n to both sides.

0.5n-1.5=0.4

Now, we will add 1.5 to both sides so all the constants are on one side.

0.5n=1.9

Now, we divide both sides by 0.5.

n=3.8

I hope this helps!
