Please help with system of equations formula creation.

A cooperative plans to create a batch of shirts in 8 days. Everyday, overfilling the norm by 10 shirts, the cooperative fulfilled his plan in 1 day less. How many shirts in a day did the cooperative have to make to fulfill his plan?

The cooperative has to make 70 shirts per day.

Step-by-step explanation:

Let x shirts be the number of shirts in a day  the cooperative has to make to fulfill his plan.

In 8 days, it will make 8x shirts.

Everyday, overfilling the norm by 10 shirts, the cooperative makes x + 10 shirts in a day.

The cooperative fulfilled his plan in 1 day less, so it spent days and made shirts.

The number of shirts is the same, so

The cooperative has to make 70 shirts per day.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
