Answer:
x

−
20
1
2
Isolate the variable by dividing each side by factors that don't contain the variable.
5x-3=21-x
6x=24
X=4
You simply have to isolate the variable and then divide by 6 so that x is completely alone.
Since y is .95 and x is 1 it is a unit rate which is the constant of proportionality.
Correct me if I am wrong.
