3x + 1 = 4x - 7
3x - 4x = -7 - 1
-x = -8
x = 8 <==

y = 3x + 1
y = 3(8) + 1
y = 24 + 1
y = 25 <===

solution is (8,25)

4 0

The answer is (8,25)
8x3=24+1=25
4x8=32-7=25

Swap x and y, f^-1 is and solve for y to get f^-1 the inverse of f. f(f^-1)=f^-1(f)=x is the identity as a check
f(2)=3*2+1=7 (2,7)
f^-1(7)=2 (7,2)
