Answer:

17

Step-by-step explanation:

substitute the values for a and b into the expression

20 - 3a + 2b

= 20 - 3(5) + 2(6)

= 20 - 15 + 12

= 5 + 12

= 17

    if a=5 and b=6, evaluate the following expression:-

      20-3a+2b

Given the expression:-

     

      [tex]\longmapsto\sf{20-3a+2b}[/tex]

To find:-

  • The simplified expression

What to do:-

  • Substitute 5 for a and 2 for b:-

[tex]\longmapsto\sf{20-3(5)+2(6)}[/tex]

On simplification,

[tex]\longmapsto\sf{20-15+12}[/tex]

On further simplification,

[tex]\longmapsto\sf{5+12}[/tex]

Finally, We get:-

[tex]\longmapsto\sf{17}[/tex]

Good luck with your studies. [tex]\ddot\smile[/tex]
