solvefor x,f(2f(-x-9))=2

solve for

x, f (2 f (- x - 9)) = 2

True for all x; 2 ff (- x - 9) = 2

Solution steps

f (2 f (- x - 9)) = 2

Simplify

f (2 f (- x - 9)) : 2 ff (- x - 9)

2 ff (- x - 9) = 2

Both sides are equal

True for all x; 2 ff (- x - 9) = 2

4 (2 x + 2 - 2) + 4 (x - 2) = 10

a, - 2 a + c = - 3

x, 2 x + 2 y = 72

3 x + 6 = 39

12 - x = \frac{1}{4} (42 - x)
