Ksenya-84 [330]

Answer:

11 invitations each

Step-by-step explanation:

Let the number of invitations they bought be x .

Since they spent the same amount of money, Their total costs would be the same. Hence ;

3.25 + 0.75(x) = 0.5x + 6

0.75x - 0.5x = 6 - 3.25

0.25x = 2.75

x = 2.75/0.25

x= 11 invitations

ira [324]

Answer:

$\large\boxed{y=\dfrac{2}{3}x-4}$

Step-by-step explanation:

$2x-3y=12\qquad\text{subtract}\ 2x\ \text{from both sides}\\\\2x-2x-3y=12-2x\\\\-3y=12-2x\qquad\text{divide both sides by (-3)}\\\\\dfrac{-3y}{-3}=\dfrac{12}{-3}+\dfrac{-2x}{-3}\\\\y=-4+\dfrac{2}{3}x$
