R = 2x + 9y [ Given ]

When,

y = 3

R = 13

★ Substituting the values in the above equation

=> 13 = 2x + 9 × 3

=> 13 = 2x + 27

=> 13 - 27 = 2x

=> -14 = 2x

=> x = -14/2

=> x = -7

Answer:

$(-1,\frac{17}{6})$

$(3,\frac{3}{2})$

$(-5,\frac{25}{6})$

Step-by-step explanation:

The given equation is $2x+6y=15$

We substitute the ordered pairs to see which ones satisfies the equation.

For (-1,-8), we put x=-1 and y=-8 to get:

$2(-1)+6(-8)=^?15$

$-2+-48=^?15\\-50=^?15$

This is not true.

For $(-1,\frac{17}{6}))$ we put x=-1 and $y=\frac{17}{6}$ to get

$2(-1)+6*\frac{17}{6})=15\\ -2+17=15\\15=15$

This is true

For (3,3/2) we have 2(3)+6(3/2)=15

This implies 6+9=15

15=15

This is also True

For (-5,25/6), we have 2(-5)+6(25/6)=-10+25=15

This is also true.
