[tex]\sf\longmapsto 5( - x) + 3 = 23[/tex]

[tex]\sf\longmapsto - 5 + 3 = 23[/tex]

[tex]\sf\longmapsto - 5x + 3 = 23 - 3[/tex]

[tex]\sf\longmapsto - 5x = 20[/tex]

[tex]\sf\longmapsto x = \frac{20}{5} [/tex]

[tex]\sf\longmapsto x = - 4[/tex]

Hope it helps ~

Step-by-step 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
