QuestionSolve for $y$ in the equation: $3x - y = 9$ .

Studdy Solution

STEP 1

Assumptions1. The equation is linear, in the form of $ax - by = c$ . . We are asked to solve for $y$ .

STEP 2

The first step is to isolate $y$ on one side of the equation. We can do this by adding $y$ to both sides of the equation.
$x - y + y =9 + y$

STEP 3

implify the equation.
$3x =9 + y$

STEP 4

Now, we need to isolate $y$ on one side of the equation. We can do this by subtracting $9$ from both sides of the equation.
$3x -9 = y$

STEP 5

So, the solution for $y$ in the equation $3x - y =9$ is $y =3x -9$ .

QuestionSolve for yyy in the equation: 3x−y=93x - y = 93x−y=9.

Studdy Solution

STEP 1

Assumptions1. The equation is linear, in the form of ax−by=cax - by = cax−by=c. . We are asked to solve for yyy.

STEP 2

The first step is to isolate yyy on one side of the equation. We can do this by adding yyy to both sides of the equation.x−y+y=9+yx - y + y =9 + yx−y+y=9+y

STEP 3

implify the equation.3x=9+y3x =9 + y3x=9+y

STEP 4

Now, we need to isolate yyy on one side of the equation. We can do this by subtracting 999 from both sides of the equation.3x−9=y3x -9 = y3x−9=y

STEP 5

So, the solution for yyy in the equation 3x−y=93x - y =93x−y=9 is y=3x−9y =3x -9y=3x−9.
