What is the value of x in the equation 2x + 1/2x + 2(1+x) = 29?
erica [24]

Answer:

<h2>x = 6</h2>

Step-by-step explanation:

2x  +  \frac{1}{2} x + 2(1 + x) = 29

Multiply through by 2

That's

4x + x + 4(1 + x) = 58

<u>Expand</u>

That's

5x + 4 + 4x = 58

9x = 58 - 4

9x = 54

Divide both sides by 9

That's

\frac{9x}{9}  =  \frac{54}{9}

We have the final answer as

<h3>x = 6</h3>

Hope this helps you
