Question

2x+y=160 , 4x+2y=300 find x and y.​

Answer 1

Answer: the system of equations has no solution.

Explanation:

`\displaystyle\\\left \{ {{2x+y=160\ \ (multiply\ both\ parts\ of\ the\ equation \ by\ 2)} \atop {4x+2y=300}} \right. \\\\\left \{ {{2x(2)}+y(2)=160(2) \atop {4x+2y=300}} \right. \\\\\left \{ {{4x+2y=320} \atop {4x+2y=300}} \right. \\\\320\\eq 300\\Hence,\ the\ system \ of\ equations\ has\ no\ solution.`

Answer 2

Explanation:

1. 2x+y=160

2. 4x+2y=300

times the first equation by 2

3. 4x+2y=320

which would mean 320=300

I don't think your equations are right
