What is the solution
Natali5045456 [20]
You would first start by eliminating one of the variables in order to find the other one.
I chose to eliminate Y, so i multiplies the second equation by -2, in order to cancel Y out.
you would then solve for X, the same you would a one step equation. X =4

You then take one of the original equations, plug X in, and solve for y. Y=5

Hope this helps!

Write the rule for the nth term of geometric sequence a1=6 and r=3
pychu [463]

Step-by-step explanation:

Hey there!

Given;

a1 = 6

and r = 3

Then;

Let's see, we have a1 "first term" and r "common ratio". So, firstly use the formula.

nth \: term \: of \: geometric \: sries =  {a}^{} . {r}^{n - 1}

Now, keep all values.

nth = 6 \times  {3}^{n - 1}

So, it becomes like this.

Therefore, the rule is nth= 6*3^n-1.

<em>Hope</em><em> </em><em>it </em><em>helps</em><em>!</em>

Please answer with clear instructions so that i can apply this to other questions.
xeze [42]

Answer:

x=10/7

Step-by-step explanation:

simplify both sides of the equation

2 * 2 + 6 = 7x

4 + 6 = 7x

combine like terms

(4 + 6) = 7x

10 = 7x

flip the equation

7x = 10

divide both sides by 7

7x/7 = 10/7

answer is 10/7
