Question

4(f-3)=20 I need help with this answer

Answer 1

F=8

Explanation:

DIVIDE BOTH SIDES BY 4

4(f-3)=20 Dividing 4(f-3) by 4 cancels out the 4 leaving it f-3

Dividing 20 by 4 =5

f-3=5 move the constant to the right (constant is the 5)

f=5+3 calculate

f=8

This is correct :)

Answer 2

f=5

Explanation:

4(f-3)=20 distribute

4f-12=20 add

4f-12+12=20+12... 4f=32 divide

4f/4=20/4..... f=5
