How can i solve this with all the work because i don't understand this?

To solve this equation, we need to get the variable x to one side of the equation and the constants (other numbers) to the other side of the equation.

11 + 2x + x = 23

First, we must add together the two variable terms on the left side of the equation to simplify, as modeled below:

11 + 2x + x = 23

3x + 11 = 23

Next, we want to cancel out the 11 on the left side of the equation, so we are going to subtract 11 from both sides of the equation.

3x + 11 - 11 = 23 - 11

3x = 12

Finally, we should divide both sides of the equation by 3 so that we can get the variable x completely alone on the left side of the equation and get rid of its coefficient.

3x/3 = 12/3

x = 4

Therefore, your answer is x=4.

Hope this helps!

ou would have 12 of each

assuming this is from a math graphing problem.

7 would be on the x-axis which is the horizontal line on the graph

84 would be on the y-axis which is the vertical line on the graph
