Answer:
x=2, x=-3, or x=3.5
Step-by-step explanation:
Make them all in 3 equations equal to 0. The number of brackets, the number of equations.

7, 14, 21, 28, 35, 42, 49... 7 cars will need. to be washed to reach $49
You add them and then it would be 30.6898033492
Let
x = 3a (first angle)
y = 3a (second angle)
z = 6a (third angle)
The total angle of a triangle is ALWAYS 180.
3a + 3a + 6a = 180
12a = 180
a = 15
Therefore, x = 45, y = 45, z = 90
