The answer your problem is X=6.
5x6+10 =40
I hope that this helps you. :)
2x + 3y = 10 -> y = -2/3x + 10/3 it's a function
4x = 16 -> x =4 it's not a function
2x - 3 = 14 -> x = 8.5 it's not a function
3y = 18 -> y = 6 it's a function
2x = 6 -> x = 3 it's not a function
Answer:
Step-by-step explanation:
tan e = x/(4x-1)
tan f = (6x+5)/(12x + 31)
since tan e = tan f
x/(4x-1) = (6x+5)/(12x+31)
x(12x+31) = (4x-1)(6x+5)
12x^2 +31x = 24x^2 +20x -6x -5
31x = 12x^2 +14x -5
0 = 12x^2 -17x -5
0 = (12x -5)(x -1)
x = 1, 5/12
