Answer:

x= 1

Explanation:

Convert 5\frac{11}{12}5

​12

​​11

​​ to improper fraction. Use this rule: a \frac{b}{c}=\frac{ac+b}{c}a

​c

​b

​​ =

​c

​ac+b

​​

3.25+0.5x+1\frac{1}{3}+\frac{5}{6}x=\frac{5\times 12+11}{12}3.25+0.5x+1

2 Simplify 5\times 125×12 to 6060

3.25+0.5x+1\frac{1}{3}+\frac{5}{6}x=\frac{60+11}{12}3.25+0.5x+1

​​


9 Simplify \frac{13.75}{3}

​3

​13.75

​​ to 4.5833334.583333

4.583333+\frac{4x}{3}=\frac{71}{12}4.583333+

​3

​4x

​​ =

​12

​71

​​


10 Subtract 4.5833334.583333 from both sides

\frac{4x}{3}=\frac{71}{12}-4.583333

​3

​4x

​​ =

​12

Answer: x = 0


Explanation:

The first step would be to convert everything to one form. I'll do the fractions, since 1/3 is hard to represent in decimal.

3 1/4 + 1/2x + 1 1/3 + 5/6x = 5 11/12

Now, the fractions will be converted via GCF. 12 is easily divisible by 4, 2, 3 and 6, so that I'll be the denominator used.

3 1/4 -> 3 3/12

1/2x -> 6/12x

1 1/3 -> 1 4/12

5/6x -> 10/12x

5 11/12 will stay the same.

The new equation is:

3 3/12 + 6/12x + 1 4/12 + 10/12x = 5 11/12

Combine like terms:

4 7/12 + 1 4/12x = 5 11/12

Subtract 4 7/12 from both sides

1 4/12x = 1 4/12

Divide both sides by 1 4/12x

x= 0
