You need to set up two equations involving two unknowns
(the weight of one shock & weight of one pad).

Have you done such problems?

Let us assume:

the weight of one shock absorber = S

the weight of one set of brake pads = B

Then we are given:

A box containing 8 shock absorbers and 10 brake pad sets weighs 101.6 lb ← convert this sentence to a mathematical equation (1)

Another box containing 10 shock absorbers and 6 brake pad sets weighs 106.2 lb ← convert this sentence to another mathematical equation (2)

Now you have two equations, (1) & (2) involving two unknowns (S and B) → solve for S & B using methods taught in your class/textbook.

Please show us what you have tried and exactly where you are stuck.
