Question

Y= -5x+1
Y=3x-2
Is (3,8) a solution of the system

Answer 1

Answer:

x = 3/8

y = -7/8

Step-by-step explanation:

y = -5x + 1

5x + y = 1

y = 3x - 2

-3x + y = -2

Elimination

5x + y = 1

-3x + y = -2

__________--

8x = 3

x = 3/8

5x + y = 1 | ×3 |

-3x + y = -2 | ×5 |

15x + 3y = 3

-15x + 5y = -10

____________+

8y = -7

y = -7/8
