Solve for r.
-30 = 5(x + 1)

-7

Step-by-step explanation:

so first we multiply 5 to the numbers in the parenthesis

-30=5X+5

then we subtract 5 from both sides

-30=5X+5

-5          -5

which equals

-35=5X

then we divide 35by5 which is 7 and since 35 is negative the answer will be

X= -7

hope you understand

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.
