Algebra-1

To determine the people of workshop A and B, we can set up a system of equations based on the given information.

Let x be the people of workshop A and y be the people of workshop B.

We know that workers in workshop A produce 30 part a and workers in workshop B produce 20 part a, so we can get 30x + 20y = 130

Similarily, workshop A produce 20 part b and workers in workshop B produce 30 part b, so we can get 20x + 30y = 120, then

1. First, simplify the system of equations: 3x + 2y = 13; 2x + 3y = 12; from first equation ,we can get y = 

2. Substitute y into the second equation: 2x + 3y = 12
