Solve by substitution:
y=x-12
8x+8y=-16

Step-by-step explanation:

we would like to solve the following system of linear equation by substitution:

notice that, we're already given the value of y therefore simply substitute it to the II equation

distribute:

simplify addition:

isolate -96 to left hand side and change its sign:

simplify addition:

divide both sides by 16 and that yields:

now substitute the got value of x to the first equation:

simplify subtraction:

hence,

the solution is (x,y)=(5,-7)

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.
