Solve the system of linear equations using elimination. - 3x - 5y = - 15 - 3x - 3y = - 3

From the equation we have:

-3x-5y=-15-3x-3y - 5y = - 15-3y 15 = 5y-3y 2y = 15 y=15/2

We also have:

-3x-5y = -3. Given y = 15/2 = > - 3x - 5 (15/2) = -3 - 3x = - 3x + 5 (15/2) = 34.5 x = 34.5/3 = 23/2 = 11.5

Answer: x = - 5; y=6

Step-by-step explanation:

-3x - 5y = - 15

-3x - 3y = - 3. (-1)

-3x - 5y = - 15

+3x + 3y = + 3

0 - 2y = - 12

y = - 12

-2

y=6

-3x - 3y = - 3

- 3x - 3.6 = - 3

-3x - 18 = - 3

-3x = 18-3

x = 15

-3

x = - 5
