Answer:
9
Step-by-step explanation:
The whole line is 180 degrees. First, you have to set up an equation. This equation would be 3x+94+x+36+2x-4=180. You can then combine like terms. The equation would now be 6x+126=180. Then subtract 126 from both sides of the equation. This would give you 6x=54. Divide 6x on both sides. The answer is 9.
2.14x - 12.18 = -5.76
Since the inverse operation of subtraction is addition, add 12.18 to both sides.
2.14x=6.42
Now, since the inverse operation of multiplication is division, divide both sides by 2.14
x=3
