4(n + 9) = -4 = ?

.

-2(3n - 5) = 34

1. n=-10 2.n=-4

Step-by-step explanation:

1. Step 1: Simplify both sides of the equation.

4(n+9)=−4

(4)(n)+(4)(9)=−4(Distribute)

4n+36=−4

Step 2: Subtract 36 from both sides.

4n+36−36=−4−36

4n=−40

Step 3: Divide both sides by 4.

n=-10

Step 1: Simplify both sides of the equation.

−2(3n−5)=34

(−2)(3n)+(−2)(−5)=34(Distribute)

−6n+10=34

Step 2: Subtract 10 from both sides.

−6n+10−10=34−10

−6n=24

Step 3: Divide both sides by -6.

n=-4

Hope this helps :)
