X = (15 - 8y)/9

-5[(15 - 8y)/9] + 12y = -107

(-75/9) + (40/9) + 12y = -107

y = -8.59

x = [15 - 8(-8.59)]/9

x = 9.3
(x,y) = (9.3, -8.59)

The inverse of F(C)=9/5C+32
Nataliya [291]
F(C) = 9/5C + 32

I'll just change F(C) to y and 9/5C to 9/5x.
y = 9/5x + 32

inverse...

x = 9/5y + 32
9/5y = x - 32
y = 5/9x - 160/9

Sooooo
F(C) = 5/9C - 160/9
