QuestionSolve for $y$ in the equation: $-18 x + 9 y = 81$ .

Studdy Solution

STEP 1

Assumptions1. The equation is linear in form, i.e., $ax + by = c$ . . We are solving for $y$ .

STEP 2

The equation given is $-18x +9y =81$ . We want to isolate $y$ on one side of the equation. To do this, we first move the term involving $x$ to the right side of the equation by adding $18x$ to both sides.
$-18x +9y +18x =81 +18x$

STEP 3

implify both sides of the equation.
$9y =18x +81$

STEP 4

Now, to solve for $y$ , we need to divide every term by $9$ .
$y = \frac{18x +81}{9}$

STEP 5

implify the right side of the equation.
$y =2x +9$ So, the solution to the equation is $y =2x +9$ .

QuestionSolve for yyy in the equation: −18x+9y=81-18 x + 9 y = 81−18x+9y=81.

Studdy Solution

STEP 1

Assumptions1. The equation is linear in form, i.e., ax+by=cax + by = cax+by=c. . We are solving for yyy.

STEP 2

The equation given is −18x+9y=81-18x +9y =81−18x+9y=81. We want to isolate yyy on one side of the equation. To do this, we first move the term involving xxx to the right side of the equation by adding 18x18x18x to both sides.−18x+9y+18x=81+18x-18x +9y +18x =81 +18x−18x+9y+18x=81+18x

STEP 3

implify both sides of the equation.9y=18x+819y =18x +819y=18x+81

STEP 4

Now, to solve for yyy, we need to divide every term by 999.y=18x+819y = \frac{18x +81}{9}y=918x+81​

STEP 5

implify the right side of the equation.y=2x+9y =2x +9y=2x+9So, the solution to the equation is y=2x+9y =2x +9y=2x+9.
