Question

Solve this system of linear equations. seperate the x- and the y- values with a coma.

(-14x=-7-7y) (-10x=-15-7y)

Answer 1

140
`x^(2)`+168xy+49
`y^(2)`+280x+154y+105

Explanation:

(−14x+−7+−7y)(−10x+−15+−7y)

=(−14x)(−10x)+(−14x)(−15)+(−14x)(−7y)+(−7)(−10x)+(−7)(−15)+(−7)(−7y)+(−7y)(−10x)+(−7y)(−15)+(−7y)(−7y)
