The difference of three times a number and 4 is negative 19 is: [tex]3u - 4 = -19[/tex]

  • Let the unknown number be u.

In this exercise, you're required to write a mathematical (algebraic) expression for the given word problem.

Translating the word problem into a mathematical (algebraic) expression, we have;

  • Three times a number = [tex]3[/tex] × [tex]u[/tex] [tex]= 3u[/tex]

Writing the complete mathematical (algebraic) expression, we have;

[tex]3u - 4 = -19[/tex]

Therefore, the difference of three (3) times a number and 4 is negative 19 is [tex]3u - 4 = -19[/tex]
