Responses
A x = 1/2

x = 1 2
B x = 1x = 1
C x = 2x = 2
D x = 4

Answer 1

To solve the equation, we can combine like terms:

3x + x + 5 = 7

Combining the x terms, we have:

4x + 5 = 7

Next, we can subtract 5 from both sides of the equation:

4x = 2

Finally, we can divide both sides of the equation by 4:

x = 2/4

Simplifying the fraction, we get:

x = 1/2

Therefore, the answer is:

A) x = 1/2
