Question

What is the result of subtracting the second equation from the first? -2x+y = 0 -7x+3y = 2

Answer 1

Answer:

-5x + 2y=2

Step-by-step explanation:

$- 7x + 3y = 2 \\ - 2x + y = 0 \\ subtracting \: this.we \: have \\ ( - 7x \: + 3y - 2) - ( - 2x + y) \\ - 7x + 2x + 3y - y - 2 \\ - 5x + 2y - 2 \\ therefore \: we \: have \\ - 5x + 2y = 2$
