Combine like terms:

$3x - x = 2x$
$2x + 2 = 12$

Subtract 2 from both sides:

$2x = 10$

Divide both sides by 2 to get x by itself:

$x = 5$

The value of x is 5.

Judging by the question I noticed that I can simplify the equation 3x-x+2=12 by one step.
The outcome of simplification should be 2x+2=12.

Next you must subtract 2 from both sides to isolate the x. The new equation should be 2x = 10.

Lastly you must divide both sides by 2, the answer you should get is x=5, D.

Your school is selling granola bars for a fundraiser. They purchased 1250 granola bars and paid a delivery fee of $25. The total

MariettaO [177]

Hello!

First we have to define a variable.

Let x stand for the price of a granola bar

Then we have to make our equation

1250x + 25 = 800

This is the equation because the price for all the granola bars and delivery was $800

Now we solve it

Subtract 25 from both sides

1250x = 775

divide 1250 from both sides

x = 0.62

The cost for a granola bar is $0.62 or 62 cents

Hope this helps!
