Solve the simultaneous equation 3x-2y=6 and 2x+y=11

Answer»

\huge\bold\green{ solution }

3x - 2y = 6 - - (1) \\ 2x + y = 11 - - (<klux>2</klux>)

equation (2)×2

3x - 2y = 6 \\ 4x + 2y = 22

____________________

7x = 28 \\ \\ x = \frac{28}{7} \\ x = <klux>4</klux>

X= 4 PUT in EQUATION (2)

2x + y = 11 \\ \\ 2 \times 4 + y = 11 \\ \\ 8 + y = 11 \\ \\ y = 3
