To make x the subject of the equation y = 3 x − 2 y=3x−2, you can isolate x x:
Start with the equation: y = 3 x − 2 y=3x−2. First, add 2 to both sides of the equation to isolate the term with 3 x 3x: y + 2 = 3 x y+2=3x. Finally, divide both sides by 3 to solve for x x: x = y + 2 3 x= 3 y+2 . So, x x is the subject of the equation y = 3 x − 2 y=3x−2, and it can be expressed as x = y + 2 3 x= 3 y+2 .
Step-by-step explanation:
y = 3x-2 add '2' to both sides of the equation to get :
y+2 = 3x Now divide both sides by 3 to get :
(y+2)/3 = x Done.
