Question

Ok- i need help! what's this ...... 6(x+9)=9

Answer 1

$\huge \boxed{\tt x= - 7.5}$

Step-by-step explanation:

• First write the equation

$\to \sf6(x+9)=9$

• Divide the 6 to 9 which is multiplying (x + 9) .

$\to \sf(x+9)= \dfrac{9}{6}$

• Divide numerator and denominator in right side by 3

$\to \sf(x+9)= \dfrac{3}{2}$

• Subtract 3/2 with 9

$\to \sf x= \dfrac{3}{2} - 9$

$\to \sf x= \dfrac{3 - 18}{2}$

• After subtracting we will get our product as - 15/2

$\to \sf x= \dfrac{ - 15}{2}$

Round of -15 / 2 to get product as - 7.5

$\to \sf x= - 7.5$

Verification:

6(x+9)=9

6(- 7.5 +9) = 9

6 × 1.5 = 9

9 = 9

Hence verified ~☆

Answer 2

Answer:

$x=-\frac{15}{2}$

Step-by-step explanation:

Start by distributing the 6 to each of the terms in the parentheses:

6(x)+6(9)=9

6x+54=9

Subtract 54 from both sides

6x+54-54=9-54

6x=-45

Divide both sides by 6

x=-45/6

Divide the fraction by 3/3 since it is the greatest common factor of 45 and 6. Note we can only do this since 3/3 is equivalent to 1, so we are essentially dividing the fraction by 1.

x=-15/2
