If you want to know what is the number of m so first you can add 2 on both sides of equation like : 13 = 5m - 2
+2 +2 ⇒ 13 + 2 = 5m ⇒ 15 = 5m ⇒ 15/5 = m ⇒ 3=m :))
i hope this be helpful
have a nice day
8y-3=6y+17
2y=20
y=10
The answer for y is 10.
You would add 5 and 1.2 which gives you 6.2 then you add negative 3.6 which then gives you 3.6.
