Answer:
x=3
Step-by-step explanation:
15 – 2x=3x
Add 2x to each side
15 – 2x+2x=3x+2x
15 = 5x
Divide each side by 5
15/5 = 5x/5
3 =x
3,5,7 are prime factors of 105
• Im sorry but we doesnt know the x number :( but dont worry to plot the diagram:
- substitute the number x (given) into the equation f(x)
- example: f(x) = x + 9 / x - 3
- then x given is 4
- therefore, f(x) = (4) + 9 / (4) - 3
- f(x) = 13 / 1 or 13
- then you plot at 13 on the graph :)
hope this helps ;/
