Question

4n-40=7(-2+2) what is the answer

Answer 1

Step 1. Simplify -2 + 2 to 0

$4n-40=7*0$

Step 2. Simplify 7 * 0 to 0

$4n-40=0$

Step 3. Add 40 to both sides

$4n=40$

Step 4. Divide both sides by 4

$n= \frac{40}{4}$

Step 5. Simplify $\frac{40}{4}$ to 10

$n=10$

Done :) Hope this helps! :)
