How many solutions does this equation have?

18 − 15t = 12 + 6 − 15t

Sagot :

Answer:

Infinity

Step-by-step explanation:

Any integer substituted for t would make the equation true.

If you solve the equation for t, you get this:

18-15t=12+6-15t

15t + 15t = 12 + 6 - 18

0t = 0  or 0 = 0

You can test this by put any integer in for t

t =0     18 - 0 = 12 + 6 +0

                18 = 18

t = - 1     18 + 15 = 12 + 6 + 15

                    33 = 33

t = 1        18 - 1 = 12 + 6 - 1

                   17  = 17
