For which value of x is the equation 2(1 + x) = x + 3 true?
A) 1
B) 2
C) 3
D) 4
I think it is c.
You think it is 3? Did you actually solve the equation to determine what it really is?
Better yet, does the value 3 work in the equation?
2(1+3) ≠ 3+3
Bzzzt. Now it's time to do the math:
2(1 + x) = x + 3
2+2x = x+3
...
Now what do you think?
Sorry I did not understand the question probably.The answer is 1 because, 2(1 +1) = 1+ 3 and both equals 4. Thank you!
To find the value of x that makes the equation 2(1 + x) = x + 3 true, we can start by simplifying the equation:
2(1 + x) = x + 3
Distribute 2 to the terms inside the parentheses:
2 + 2x = x + 3
Next, let's isolate the variable x by moving all the terms containing x to one side of the equation and the constant terms to the other side:
2x - x = 3 - 2
Simplify:
x = 1
Therefore, the value of x that makes the equation true is 1. So the correct answer is A) 1.
