What is this answer? 3(2x+ 1) + x= -39

x = 6

Step-by-step explanation:

3 (2 x + 1) + x = -39

3 (2 x + 1) = 6 x + 3:

6 x + 3 + x = -39

Grouping like terms, 6 x + x + 3 = (6 x + x) + 3:

(6 x + x) + 3 = -39

6 x + x = 7 x:

7 x + 3 = -39

Subtract 3 from both sides:

7 x + (3 - 3) = -3 - 39

3 - 3 = 0:

7 x = -3 - 39

-3 - 39 = -42:

7 x = -42

Divide both sides of 7 x = -42 by 7:

(7 x)/7 = (-42)/7

7/7 = 1:

x = (-42)/7

The gcd of -42 and 7 is 7, so (-42)/7 = (7 (-6))/(7×1) = 7/7×-6 = -6:

 x = -6

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
