Question

-6n-20=-2n+4 (1-3n) how do you solve it?

Answer 1

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

Answer 2

-6n - 20 = -2n + 4(1-3n)

-6n - 20 = -2n + 4 - 12n 
-6n + 12n + 2n = 4+20

8n = 24     |:8
