Question

y = -6x + 5
12x + 2y -= 5

Solve each system by substitution.

Answer 1

Answer:

y = -6x + 5

12x + 2y -= 5

Solve each system by substitution.

add equation 1 from 2

-6x+5= y

12x+2y= 5

-6x+5-y+12x+2y=5

-6x+12x-y+2y+5-5= 0

6x-y= 0

y= 6x

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

Y = -6x + 5

12x + 2y =- 5

from equation i, y= -6x+5

12x + 2( -6x+5 ) = -5

12x-12x+10 = -5

0 = -5-10 = -15

it is null
