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

Mathematics

erica [24]3 years ago
5 0

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

How do you solve 3 1/4- 1 7/8 step by step?
Vilka [71]

Answer:

1 3/8.

Step-by-step explanation:

3 1/4 - 1 7/8

First convert to improper fractions:

3 1/4 = (3*4) + 1 / 4 =  13/4.

1 7/8 = (1 *8)+7 / 8 = 15/8. So we have:

13/4 - 15/8

The Lowest Common Multiple of 4 and 8 is 8 so we convert 13/4 to eighth's

13 / 4 = 13*2 / 4 *2 = 26/8

Finally: we have

26/8 - 15/8 = (26 - 15) /8

= 11 /8

= 1 3/8 (answer)

grigory [225]

Answer:

no solutions

Step-by-step explanation:

<u>Solving</u>

Step 1: Subtract 3 from both sides.

  • r+3-r=r-5-r
  • 3=-5

Step 2: Subtract 3 from both sides.

  • 3-3=-5-3
  • 0\neq -8

Therefore, there are no solutions to this equation.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
