Solve this system of linear equations. seperate the x- and the y- values with a coma.
(-14x=-7-7y) (-10x=-15-7y)

140+168xy+49+280x+154y+105

Step-by-step 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)

step-by-step explanation:

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
