Question

-3+3n=-7+2n
show me how u got that answer

Answer 1

→ Chapter : Linear Equation of One Variable ←
≡ Solution:
⇒
`-3+3n=-7+2n`
⇒
`3n-2n=-7+3`
⇒
`\boxed{n=-4}`

Answer 2

-3+3n = -7+2n
-3+(3n-2n) = -7+(2n-2n)
since you subtracted 2n from both sides, 2n cancels out on the right side so you're left with
-3+n = -7
n = -7+3 = -4
