For which value of x is the equation 2(1 + x) = x + 3 true?<br><br> A) 1<br> B) 2<br> C) 3<br> D) 4
amm1812

Answer:

A) 1

Step-by-step explanation:

To solve, just plug in the numbers to the equation for x until both sides are equal to each other.

Plug in 1:

2(1 + x) = x + 3

Let x = 1:

2(1 + 1) = 1 + 3

Solve. Remember to follow PEMDAS. First, add parenthesis, then multiply. On the other side, add:

2(1 + 1) = 1 + 3

2(2) = 4

4 = 4 (True)

A) 1 is your answer.
