Divide them and you're answer will come out
Answer:
For example, 8f + 4g is one of the most used expression
Another example is 4 (2f + g), is correct too
7/16 + 3/8 + Blank = 1
7/16 + 6/16 + 3/16 = 1
convert 3/8 to 6/16 then add 7+6 which = 13
that would be 13/16 then figure out that 13+3 =16 so 13/16+3/16= 16/16 or 1
y=-x-5. you just need to add 1 to another side to get rid of 1 from the left side
