cheater == 2[x-3]+3[x-2]=18 2x-6+3x-6=18 5x-12=18 5x=30 x=30/5=6
Follow this example. f(x) = (x+3)/5 To find its inverse, write y=f(x) y= (x+3)/5 Interchange x and y x = (y+3)/5 solve for y in terms of x 5x=y+3 y=5x-3 The inverse of f(x) is f^-1(x) = 5x-3
3/5x + 22 = 28 To solve this: Subtract 22 from both sides: 3/5x = 6 Multiply by 5x: 3 = 6*5x Divide by 6: 3/6 = 5x Divide by 5: (3/6)/5 = x Work it out: 3/6 = 0.5 0.5/5 = 0.1 x = 0.1
