What is the value of 2x in this equation<br> 5x - 2(2x - 1) = 2(3x - 4)
KiRa [710]

Answer:

4

Step-by-step explanation:

Step 1: Write equation

5x - 2(2x - 1) = 2(3x - 4)

Step 2: Solve for <em>x</em>

  1. Distribute: 5x - 4x + 2 = 6x - 8
  2. Combine like terms: x + 2 = 6x - 8
  3. Subtract x on both sides: 2 = 5x - 8
  4. Add 8 to both sides: 10 = 5x
  5. Divide both sides by 5: 2 = x
  6. Rewrite x = 2

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

5(2) - 2(2(2) - 1) = 2(3(2) - 4)

10 - 2(4 - 1) = 2(6 - 4)

10 - 2(3) = 2(2)

10 - 6 = 4

4 = 4

Here we see that x = 2 is indeed a solution

Step 4: Find 2x

2(2) = 4

Which of the following graphs represent the equation y=3x+2
seropon [69]

Answer:You haven't attached a picture but this is what your line should look like

Step-by-step explanation:

For this equation you simply have to graph it.

First, you have to remember that these equations follow a formula: y=mx+b. m is the slope of you line and b is the y-intercept.

Next, you need to graph it. First, graph your b, in this case 2. You would go up 2 on you graph (graph (0,2)). Then, you would graph your slope which is 3.

Now, remember that slope equals y/x, so think of the number 3 being like 3/1. You would start at (0,2) and go up 3 points in the graph, then over 1 point (graph where you end up). You repeat that from each new point you make until you have enough points to create a straight line.

Hope this helps a bit,
