Question

Slove the equation 3n+2=-2n-8

Answer 1

lets use 5 as n for example
if this would be "find out if the equation is true"
3(5) = 15 + 2 = 17
-2(5) = -10 - 8 = -18
false
lets find out the number n
lets use -1
3(-1) -3 + 2 = -1
-2(-1) 2 - 8 = -6
-2
3(-2) -6 + 2 = -4
-2(-2) = 4 - 8 = -4
if we were looking for n its -2.
answers: false or -2.

Answer 2

3n+2=-2n-8
3n+2+2n = -8
5n = -8 -2
5n = -10
n = -2
