Solve for x, simplifyb. 1+2x-x= x-5+x

Start by combining the like terms on both sides of the equation.  On the left, the like terms are 2x and -x (because both contain an x), and on the right, the like terms are x and x (both contain an x).

Left:

2x-x=x

Right:

x+x=2x

Now, the equation reads: 1+x=-5+2x.  You now need to isolate the variable by subtracting x from both sides:

1=-5+x

You can solve this like any other equation:

*Add 5 to both sides*

6=x

The answer is x=6.

Hope this helps!!

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

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
