I hope I’m not too late. Substitute x = 4y + 5y = 2
y = 2. Substitute this value into the first equation: x + -4 x 2 = -8. So the answer is (-8,2).

A bouquet of 8

A rose costs $2.5 and a carnation costs $3.

Step-by-step explanation:

Let,

Roses = x

Carnations = y

According to given statement;

8x+10y=50  Eqn 1

6x+12y=51    Eqn 2

Multiplying Eqn 1 by 6;

6(8x+10y=50)\\48x+60y=300\ \ \ Eqn\ 3\\

Multiplying Eqn 2 by 8;

8(6x+12y=51)\\48x+96y=408\ \ \ Eqn 4

Subtracting Eqn 3 from Eqn 4;

(48x+96y)-(48x+60y)=408-300\\48x+96y-48x-60y=108\\36y=108

Dividing both sides by 36;

\frac{36y}{36}=\frac{108}{36}\\y=3

Putting y=3 in Eqn 3;

48x+60(3)=300\\48x+180=300\\48x=300-180\\48x=120

Dividing both sides by 48;

\frac{48x}{48}=\frac{120}{48}\\x=2.5

A rose costs $2.5 and a carnation costs $3.
