Question

8x + 13y = 2

y = x- 2
Solve the system of equations

(4/3, -2/3)
(4/21, -38/21)
no solution

Answer 1

A) (4/3, -2/3)

Explanation:

8x + 13y = 2

y = x- 2

8x+13 (x-2) =2

distribute:

8x+13x-26=2

21x-26=2

21x-26+26=2+26

21x=28

21x/21=28/21

28/21 simplified by 7 is 4/3

now lets find y

y=x-2

we know that x is 4/3

y=4/3-2

y=-2/3

so the answer is (4/3,-2/3)

Answer 2

eliminationg these equations gives zero ,no solution
