Find the input (x) of the function y = 1/4x+ 12 if the output
(y) is 6

Answer:
x = -24
Step-by-step explanation:
y = 1/4x+12 (Substitute 6 for y)
6 = 1/4x+12 (Subtract 12 from both sides)
6-12= -6 so its now -6 = 1/4x and since its a fraction you want to multiply both sides by the reciprocal
4*-6 = 1/4x*4 (1/4*4=1 which is 1x or x)
-24 = x
Answer:
y=1/4x+12
6=1/4x+12
1/4x=6-12
1/4x=-6
0.25x=-6
x=-6÷0.25
x=-24
