Step-by-step explanation:

idk your answer sorry Btw how r u

x = 6, y = - 7

Step-by-step explanation:

Given the 2 equations

10x - 3y - 81 = 0 ( add 81 to both sides )

10x - 3y = 81 → (1)

- 5x - 7y - 19 = 0 ( add 19 to both sides )

- 5x - 7y = 19 → (2)

Multiplying (2) by 2 and adding to (1) eliminates the term in x

- 10x - 14y = 38 → (3)

Add (1) and (3) term by term

- 17y = 119 ( divide both sides by - 17 )

y = - 7

Substitute y = - 7 into either of the 2 equations for corresponding value of x

Substituting into (1)

10x - 3(- 7) = 81

10x + 21 = 81 ( subtract 21 from both sides )

10x = 60 ( divide both sides by 10 )

x = 6
