3x –2.6 = x + 8.2 i need some help pls

Hi there!!

x = 5.4

Step-by-step explanation:

So, first thing you'd wanna do here is combine the like variables. So, you'd add the x to the 3x on the other side of the equation. This makes the equation 4x - 2.6 = 8.2

Next, you'd want to begin isolating the x variable. To do this, you would want to eliminate the 2.6 by adding it to both sides of the equation. This would make the equation 4x = 10.8

Now, to finish isolating the x variable, you would divide both sides of the equation by 4. This would make the equation x = 5.4, and that's your final answer.

I hope this helps!

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
