What is the answer to<br> -2a-9=6a+15

timurjin [86]

Answer:

$a=-3$

Step-by-step explanation:

$-2a-9=6a+15$

Add 9 to both sides:

$-2a-9+9=6a+15+9$

$-2a=6a+24$

Subtract 6a from both sides:

$-2a-6a=6a+24-6a$

$-8a=24$

Divide both sides by -8:

$\frac{-8a}{-8}=\frac{24}{-8}$

$a=-3$

Leona [35]

Answer:

<A = 35 degrees

Step-by-step explanation:

<A = x

<B = 2x

<C = 2x + 5

X + 2x + 2x + 5 = 180 degrees

5x + 5 = 180

5x = 180 -5

x = 175/5

x = 35
