Simplify the expression 2x+x+x+x

5x

Step-by-step explanation:

Let's solve the question

2x+x+x+x

This means that we will have to add the whole values having the x variables

The main reason why we will have to add is because the have the same variables

So back to the question

2x+x+x+x

It gives 5x

Therefore the final answer is 5x

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
