Answer:
In step 2, he needed to divide both sides of the equation by 5
Step-by-step explanation:
we have
![5a+2b=10](https://tex.z-dn.net/?f=5a%2B2b%3D10)
Solve for a------> That means isolate the variable "a"
step 1
Subtract 2b to both sides
![5a+2b-2b=10-2b](https://tex.z-dn.net/?f=5a%2B2b-2b%3D10-2b)
![5a=10-2b](https://tex.z-dn.net/?f=5a%3D10-2b)
step 2
Divide by 5 both sides
![5a/5=(10-2b)/5](https://tex.z-dn.net/?f=5a%2F5%3D%2810-2b%29%2F5)
![a=(10-2b)/5](https://tex.z-dn.net/?f=a%3D%2810-2b%29%2F5)
