F(x) = 7x - 13
y = 7x - 13
7x - 13 = y
7x = y + 13
x = (y + 13)/7
f^-1(x) = (x + 13)/7

Answer:

x=16°

Step-by-step explanation:

5*x-30=2*(x+18)

For the second, I'd say it is:

5*x-30=2*x+18

Let's solve both.

5*x-30=2*(x+18)

5x-30=2x+36

3x=66

x=22

5*x-30=2*x+18

3x+48

x=16°

121/2 = 60.5.....so < W = 60.5 and < X = 60.5
