Question

Maddox has 21 to spend on souverniers as gift for his friends. He wants to buy each friend a keychain and a pin. The equation 3f + 4f =21 can be used to find f, the number of friends for which he can buy souvenirs

Answer 1

here’s the answer

3f + 4f = 21
add the 3f + 4f
7f = 21
divide each side by 7 to cancel the f out
7f/7 = 21/7
f=3
therefore maddox has 3 friends that he can buy souvenirs for

Answer 2

`\huge\textbf{Hey there!}`

`\mathsf{3f + 4f = 21}`

`\textbf{COMBINE the LIKE TERMS}`

`\mathsf{(3f + 4f) = 21}`

`\mathsf{3f + 4f = 21}`

`\mathsf{7f = 21}`

`\textbf{DIVIDE 7 to BOTH SIDES}`

`\mathsf{(7f)/(7) = (21)/(7)}`

`\textbf{SIMPLIFY it!}`

`\mathsf{f = (21)/(7)}`

`\mathsf{f = 3}`

`\huge\textbf{Therefore, your answer should be: }`

`\huge\boxed{\mathsf{f = 3}}\huge\checkmark`
