Answer: x = 4 and y = -3

Step-by-step explanation:

2x + 4y = -4

2x = -4 - 4y

x = -2 - 2y

Now that we have solved the first equation for x, we plug (-2 - 2y) into the other equation in place of x and then solve for y.

3(-2 -2y) + 5y = -3

-6 - 6y + 5y = -3

-y = 3

y = -3

Now that we know y, we plug it into the original equation and solve for x.

2x + 4(-3) = -4

2x + -12 = -4

2x = 8

x = 4

You can check the answer by plugging both x and y into either of the original equations.

nlexa [21]

Answer:

11, 5

Step-by-step explanation:

x=y-6

xy=55

Put x as y-6 in the second equation.

(y-6)y=55

y^2-6y=55

y^2-6y-55=0

Factor.

\left(y+5\right)\left(y-11\right)=0

\left(y+5\right)=0

y=-5

It has to be a positive integer.

y-11=0

y=11

Substitute y as 11.

x=y-6

x=11-6

x=5
