Step-by-step explanation:

Let's solve your system by substitution.

3x−2y=7;y=x+2

Rewrite equations:

y=x+2;3x−2y=7

Step: Solvey=x+2for y:

y=x+2

Step: Substitutex+2foryin3x−2y=7:

3x−2y=7

3x−2(x+2)=7

x−4=7(Simplify both sides of the equation)

x−4+4=7+4(Add 4 to both sides)

x=11

Step: Substitute11forxiny=x+2:

y=x+2

y=11+2

y=13(Simplify both sides of the equation)

x=11 and y=13

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.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
