Alex has $20, and ellen has $12. alex is saving $3 per day, and ellen is saving $5 per day. after how many days will alex and ellen have the dame amount of money?

4 days

I used this equation to solve the problem

3x + 20 = 12 + 5x

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
