Solve followingsimultenous by subs8x+3y=11,3x-y=2​

Answer» ONG>Answer:

x=-5

y=-17

Step-by-step explanation:

8x - 3y = 11 \\ 3x - y = 2

Are the GIVEN equations

Solving these equations,

(8x - 3y = 11) \times 1 \\ (3x \ -  y = 2) \times 3 \\  \\ (8x - 3y = 11) \\ (9x  - 3y = 6) \\  \\  - x = 5  \\ x =  - 5

Substituting x in the FIRST EQUATION,

8( - 5) - 3y = 11 \\  - 40 - 3y = 11 \\  - 3y = 11 + 40 \\  - 3y = 51 \\ y =  \frac{51}{ - 3}  \\ y =  - 17

THEREFORE, x=-5

y=-17
