Question

I need a bit of help

Answer 1

Substitute r = 2 and s = 3 into the expression:

5r + 7s - 3(r + s) + 4 = 5(2) + 7(3) - 3(2 + 3) + 4

= 10 + 21 - 15 + 4

= 20

Therefore, the value of the expression when r = 2 and s = 3 is 20.

Answer 2

Given:-

• 
  `\texttt{r = 2}`

`\:`

• 
  `\texttt{s = 3}`

`\:`

Solution:-

• 
  `\texttt{5r+ 7s - 3( 2 + 3 ) + 4}`

`\:`

put the given values in the equation

• 
  `\texttt{5( 2 ) + 7 ( 3 ) - 3( 2 + 3 ) + 4.}`

`\:`

• 
  `\texttt{10 + 21 - 6 - 9 + 4}`

`\:`

• 
  `\texttt{31 - 15 + 4}`

`\:`

• 
  `\texttt{16 + 4}`

`\:`

• 
  `\texttt{ \red{20}} \:`

`\:`
