Answer:

x = 9

Step-by-step explanation:

Find common denominator

[tex]\frac{d}{3} +\frac{3*9.9}{12.9}[/tex]

Combine fractions with common denominator

[tex]\frac{d+3*9.9}{3} =12.9[/tex]

Multiply the numbers

[tex]\frac{d+29.7}{3} =12.9[/tex]

Multiply all terms by the same value to eliminate fraction denominators

[tex]3(\frac{x+29.7}{3} )=3 * 12.9[/tex]

Cancel multiplied terms that are in the denominator

x=29.7= 3 · 12.9

Multiply the number

x= 12.9=38.9

Subtract 297 from both sides of the equation

x+29.7-29.7=38.9-29.7

Simplify

x = 9.0

Hence, the answer is 9.
