Question Find the value of $y$ when $x=2$ in the linear equation $y=\frac{5}{2}x-9$ .

Studdy Solution

STEP 1

Assumptions1. The equation is $y=\frac{5}{} x-9$ . The value of $x$ is given as $$

STEP 2

We need to substitute the value of $x$ into the equation to find the value of $y$ . $y = \frac{5}{2} x -9$

STEP 3

Substitute $x =2$ into the equation.
$y = \frac{5}{2} \cdot2 -9$

STEP 4

Perform the multiplication operation.
$y = -9$

STEP 5

Perform the subtraction operation to find the value of $y$ .
$y =5 -9 = -4$ So, the value of $y$ when $x=2$ in the equation $y=\frac{5}{2} x-9$ is $-4$ .

Question Find the value of yyy when x=2x=2x=2 in the linear equation y=52x−9y=\frac{5}{2}x-9y=25​x−9.

Studdy Solution

STEP 1

Assumptions1. The equation is y=5x−9y=\frac{5}{} x-9y=5​x−9 . The value of xxx is given as $$

STEP 2

We need to substitute the value of xxx into the equation to find the value of yyy.y=52x−9y = \frac{5}{2} x -9y=25​x−9

STEP 3

Substitute x=2x =2x=2 into the equation.y=52⋅2−9y = \frac{5}{2} \cdot2 -9y=25​⋅2−9

STEP 4

Perform the multiplication operation.y=−9y = -9y=−9

STEP 5

Perform the subtraction operation to find the value of yyy.y=5−9=−4y =5 -9 = -4y=5−9=−4So, the value of yyy when x=2x=2x=2 in the equation y=52x−9y=\frac{5}{2} x-9y=25​x−9 is −4-4−4.
