2x-2=x+45 <br> Can someone figure out the value of x?
Andre45 [30]

Answer:

<h3>x=47</h3>

Step-by-step explanation:

To solve this problem, first, you have to isolate x on one side of the equation. Isolate it on one side of the equation.

2x-2=x+45

2x-2+2=x+45+2 (First, add 2 from both sides.)

45+2 (Solve.)

45+2=47

2x=x+47

2x-x=x+47-x (Then, subtract x from both sides.)

47-x (Solve.)

47-x=47

x=47

In conclusion, the final answer is x=47.

Tanya [424]

Answer:

f(x) = (x − 1)(x − 2)(x − 3)

Step-by-step explanation:

through the x axis at one; x = 1    factor (x - 1)

through the x axis at two; x = 2    factor (x - 2)

through the x axis at three;  x = 3    factor (x - 3)

f(x) = (x − 1)(x − 2)(x − 3)

Solve the following equation. Determine if the equation is an "identity" or "contradiction."
Leona [35]
To solve, we must get x by itself. the first step we must take is to remove all of the parentheses. To do this, we must use distribution to multiply 5 by x - 6.

5(x - 6) = 3x - 18 + 2x

5x - 30 = 3x - 18 + 2x

Next, we must add like terms.

5x - 30 = 5x - 18

Finally, we must get x by itself. to do this, we must subtract 5x from both sides.

5x - 30 - 5x = 5x - 18 - 5x

Then, we add like terms again.

-30 = -18

Because this is a false statement, the equation is a contradiction.
