Answer:

x = 14

Step-by-step explanation:

Okay so the equation looks like this:

X/-2 = -7

In order for us to get rid of the -2 we are going to have to multiply -2 on both sides of the equal sign, so that we only have x on one side of the equal sign and numbers on the other:

X/-2 = -7

 *-2  *-2

since multiplying or dividing a negative number by a negative number gives you a positive -7 is going to become 14 and x remains on the other side of the equal sign:

x = 14

Now to check our work we are going to place 14 where the x variable is in the equation:

X/-2 = -7 or (14)/-2 = -7

-7 = -7

Hope this helps you!!

Solve ax + b = cx + d for x.
romanna [79]

Answer: X = (d-b) / (a-c)

This way this worded is weird but I think I got it

Step-by-step explanation:

Subtract B from both sides

ax = cx +d -b

Then subtract CX from both sides

ax -cx =d-b

Distributive Property

x(a-c) =d-b

Divide both sides by a-c

X = (d-b) / (a-c)

Write the explicit rule,
meriva

Answer:

a_{n} = 20n + 12

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 52 - 32 = 72 - 52 = 92 - 72 = 20

This indicates the sequence is arithmetic with explicit formula

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 32 and d = 20, thus

a_{n} = 32 + 20(n - 1) = 32 + 20n - 20 = 20n + 12
