1) 3x-8 =x
subtract x from both sides
2x-8=0
add 8 to each side
2x=8
divide both sides by 2
x=4
Answer:
The inverse is 1/2x -3/2
Step-by-step explanation:
Set the equation equal to y
y = 2x+3
Exchange x and y
x = 2y+3
Solve for y
Subtract 3 from each side
x-3 = 2y+3-3
x-3 = 2y
Divide each side by 2
(x-3)/2 = 2y/2
1/2x -3/2 =y
The inverse is 1/2x -3/2
