$\bf 9\left(2x+1\right)=\:9x-18$

Answer 1

$\qquad\qquad\huge\underline{{\sf Answer}}$

$\textbf{Here we go :}$

$\qquad \sf \dashrightarrow \:9(2x + 1) = 9x - 18$

$\qquad \sf \dashrightarrow \:18x + 9 = 9x - 18$

$\qquad \sf \dashrightarrow \:18x - 9x = - 18 - 9$

$\qquad \sf \dashrightarrow \:9x = - 27$

$\qquad \sf \dashrightarrow \:x = - 27 \div 9$

$\qquad \sf \dashrightarrow \:x = - 3$

$\textsf{Hence, value of x is -3}$

Answer 2

9(2x+1)=9x-18
•Apply the Distributive Property
18x+9=9x-18
•Rearrange variables the the left side of the equation
18x-9x=-18-9
•Combine like terms
9x=-18-9
•Calculate the sum or difference
9x=-27
•Divide both sides
x= -27/-9
•Cross out the common factor

x=-3
