Check the picture below.

a+b=180\implies b=180-a \\\\\\ \stackrel{\textit{substituting on the 2nd equation}}{a-39=2(180-a)}\implies a-39=360-2a\implies 3a-39=360 \\\\\\ 3a=321\implies a = \cfrac{321}{3}\implies \boxed{a = 107}~\hfill \boxed{\stackrel{180-107}{b = 73}}

What is the answer plz show your work <br> 5(k-2)-8k=-34
Rina8888 [55]
Let's solve your equation step by step.

5(k - 2) - 8k= -34

Step 1: Simplify both sides of the equation.

5(k - 2) - 8k= -34

(5)(k) = (5)(-2) + - 8k= -34 (Distribute)

5k + -10 + -8k = -34

(5k + -8k) + (-10) = -34 (Combine Like Terms)

-3k + -10 = -34

-3k - 10 = -34

Step 2: Add 10 to both sides.

-3k - 10 + 10 = -34 + 10

-3k = -24

Step 3: Divide both sides by -3.

-3k\3 =-24\-3

K= 8

Answer:
