3x + 1 + 5x = 7 +15 + 7x

Move unknown terms to the left of the equal with changed sign and the known terms to the right of the equal with changed sign.

3x + 5x - 7x = 7 + 15 - 1

x = 21

Combine like terms on each side of the equation...

8x+1=7x+22  subtract 1 from both sides

8x=7x+21  subtract 7x from both sides

x=21

Answer:

Step-by-step explanation:

Remark

My guess is that what is confusing you is not what you have to do, but why it is disguised as g(n)

What you are doing in effect is setting up a table. You are also not certain where the table starts. And that is a problem. I will start it at zero, but it might be 1.

zero

n = 0

g(0) = 34 - 5*0

g(0) = 34

One

n = 1

g(1) = 34 - 5*1

g(1) = 34 - 5

g(1) = 29

Two

g(2) = 34 - 5*2

g(2) = 34 - 10

g(2) = 24

Three

g(3) = 34 - 5*3

g(3) = 34 - 15

g(3) = 19

Four

g(4) = 34 - 5*4

g(4) = 34 - 20

g(4) = 19

Answer

0      1       2       3      4

34  29     24     19     14

Which sentence explains the correct first step in the solution of this equation?<br><br> 4(x−3)=9
kodGreya [7K]

Answer:

You will do the Distributive Property first.

Step-by-step explanation:

You will do the Distributive Property first.

4(x - 3) = 9 <u>distribute the 4 into the x and -3.</u>

4x - 12 = 9 <u>add -12 to both sides.</u>

4x = 21 <u>divide 4 on both sides.</u>

x = 5.25 is your answer.
