-6n-20=-2n+4 (1-3n)
how do you solve it?
2 answers:
6n−20=−2n+4(1−3n)
Simplify both sides of the equation.
−6n−20=−2n+4(1−3n)
−6n+−20=−2n+(4)(1)+(4)(−3n)(Distribute)
−6n+−20=−2n+4+−12n
−6n−20=(−2n+−12n)+(4)(Combine Like Terms)
−6n−20=−14n+4
−6n−20=−14n+4
Add 14n to both sides.
−6n−20+14n=−14n+4+14n
8n−20=4
Add 20 to both sides.
8n−20+20=4+20
8n=24
Divide both sides by 8.
8n/8 = 24/8
n=3
-6n - 20 = -2n + 4(1-3n)
-6n - 20 = -2n + 4 - 12n
-6n + 12n + 2n = 4+20
8n = 24 |:8
n=3
