6x − 3y = 7, −2x + y = −8 <br><br> x=?<br> y=?
kap26 [50]

Answer:

no solution

Step-by-step explanation:

6x - 3y = 7 → (1)

- 2x + y = - 8 → (2)

multiplying (2) by 3 and adding to (1) eliminates the variables

- 6x + 3y = - 24 → (3)

add (1) and (3) term by term

0 + 0 = - 17

0 = - 17 ← false statement

This indicates the system has no solution
