At general Electric, shift 1 produced 4 times as much as shift 2. General Electric’s total production for July was 5,500 jet engines. What was the output for each shift.

I can not figure this out could someone help please.

You can see it as if shift one produced 4 parts and shift 2 one part. Total is 5 parts. Therefore, shift one produced 4400 engines and shift 2 1100.

If shift one produced x and sift two y, the total production was

x+y=5500

you also know that x=4y, substitute and you get

5y=5500 => y=1100
