Solve the pair of simultanous equation. 2x +3y=5. x+y=1

(-2;3)

Step-by-step explanation:

x=1-y

2*(1-y)+3y=5

y=3

x=-2

grab rope, tie a loop-de-loop, put it around ur neck, now jump while its tied to a high place. now your shoes are cool.

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
