you can - or + the equation only then when the letter is same z and z both are same so you can - them and get the answer.
Answer:
1 solution
Step-by-step explanation:
4x + x + 3 = 4x (Subtract 4x from both sides)
x + 3 = 0 (Subtract 3 from both sides)
x = -3

so as you can see the common ratio is 2, and the first term is 1/2,

t(f) = 27*f
g(t) = $0.04*27*f
without the value for f (the number of friends) that is the farthest this can be solved.
