[tex]Answer:[/tex]
If the "problem of 3 and a number [tex]z[/tex]" is multiplying: [tex]4+(3z)[/tex]
If it's about adding: [tex]4+(3+z)[/tex]
[tex]Step-by-step[/tex] [tex]explanation:[/tex]
Scenario A: If it's 3 and z, then that means it's 3[tex]z[/tex], and we're adding 4, so it's [tex]4+(3z)[/tex] (make sure to put () around the 3[tex]z[/tex]!)
Scenario B: If 3 and z is also 3+[tex]z[/tex], then the equation is [tex]4+(3+z)[/tex] (also use () on this too!)
