Question

`\sf How \; do \; you\; solve\; this?`

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

Answer 1

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

Answer 2

`\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 / 9`

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

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