5\left(9-x\right)+3=23

Explanation:

Given that:

5(9 - x) + 3 = 23

Multiply the number outside of the bracket with numbers in the bracket on LHS.

⇛45 - 5x + 3 = 23

Shift constants from LHS to RHS, changing it's sign.

⇛-5x = 23 - 45 - 3

⇛-5x = 23 - 42

⇛-5x = -19

Shift the number 5 from LHS to RHS.

⇛x = -19/-5

Therefore, x = 19/5

Please let me know if you have any other questions.

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


\sf\longmapsto 5( - x) + 3 = 23


\sf\longmapsto - 5 + 3 = 23


\sf\longmapsto - 5x + 3 = 23 - 3


\sf\longmapsto - 5x = 20


\sf\longmapsto x = (20)/(5)


\sf\longmapsto x = - 4

Hope it helps ~
