The scenario represents a linear function. The rate is at a constant increase therefore it is linear.
Linear because it’s a constant rate

Exponential since it increases by a multiplicative rate. It’s not constant
Divide by 5 each side
X+2=4
Subtract 2 from each side
X=2
5(2+2)=20
Does work
In algebra when isolating (leaving alone on one side) x, you do the opposite operation, thus multiplying when you are trying to get rid of a division and vice versa
