Step 1: Rewrite the equation

3y+x=12

Step 2: To get y alone on the left side, subtract x on both sides

3y+x=12
-x -x
______
3y=-x+12

Step 3 (final step): To get y alone, divide each number by 3

3y = -x +12
/3 /3 /3
________
y=-1/3x+4

Final answer: y=-1/3x+4

Hope this helps :)

What is the inverse of x-2

SCORPION-xisa [38]

Answer:

y = x + 2

Step-by-step explanation:

The expression x-2 is from the equation y = x - 2.

To find the inverse of the equation, <u>switch the "x" and "y" variables</u>, then solve or <u>isolate for "y"</u>, meaning to separate it from the other numbers.

y = x - 2 Original equation

x = y - 2 Switched "x" and "y" variables

x + 2 = y - 2 + 2 Add 2 to both sides to cancel out '-2' on the side with "y"

x + 2 = y

y = x + 2 Variable is on left side in standard formatting

To isolate, do the reverse operation for the number you want to get rid of.

On the side with "y", I wanted to get rid of '-2' so I could separate "y" from everything else. '+2' is the reverse operation for '-2'.
