Answer:
x = -4
Step-by-step explanation:
combine like terms
-10x - 3 - 2.5x + 20 = 67
-12.5x + 17 = 67
subtract 17 from both sides of the equal sign
-12.5x = 50
divide -12.5 from both sides of the equal sign
x = -4

Answer:
x = -6
Step-by-step explanation:
Here we have an equilateral triangle. All three sides have the same length, 2. Therefore, the interior angles are all equal to 60 degrees.
Therefore, 6 - 9x = 60, and -9x = 54. Dividing both sides by -9 results in
x = -54/9, or x = -6.
