Answer:
12e + f
Step-by-step explanation:
2f - f = f
9e + 3e = 12
....
f + 12e
Step-by-step explanation
(+2f) + (+9e) + (-f) + (+3e)
(2f) + (-f) = 1f or f
9e + 3e = 12e
(4 x 3) x 2==12 x 2
=24
If the "problem of 3 and a number " is multiplying:
If it's about adding:
Scenario A: If it's 3 and z, then that means it's 3, and we're adding 4, so it's (make sure to put () around the 3!)
Scenario B: If 3 and z is also 3+, then the equation is (also use () on this too!)
