Step-by-step explanation:

x = jars of alfalfa

y = jars of blueberry

z = jars of cover

x + y + z = 1450

x = y + 130

z = 2x

the easiest is now to turn the main equation into an expression of one variable (I am going for x).

for this let's transform the second equation

x = y × 130

y = x - 130

so now we have expressed y and z as terms of x.

back to the main equation :

x + x - 130 + 2x = 1450

4x = 1580

x = 395

he has 395 jars of alfalfa honey.
