10x-3y-81=0 -5x-7y-19=0

I need the values for x and y plz

x = 6, y = - 7

Step-by-step explanation:

Given the 2 equations

10x - 3y - 81 = 0 → (1)

- 5x - 7y - 19 = 0 → (2)

Multiplying (2) by 2 and adding to (1) will eliminate the x- term

- 10x - 14y - 38 = 0 → (3)

Add (1) and (3) term by term

- 17y - 119 = 0 ( add 119 to both sides )

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

y = - 7

Substitute y = - 7 into either of the 2 equations

Substituting y = - 7 into (1)

10x - 3(- 7) - 81 = 0

10x + 21 - 81 = 0, that is

10x - 60 = 0 ( add 60 to both sides )

10x = 60 ( divide both sides by 10 )

x = 6

the two may have that, even a breakdown is probably offered

16.80 times .20= 3.36
