Answer:
The answer is B
Step-by-step explanation:
2x+2y =10 and y= -x +5
These are not in the same form so thats the first step
2x+2y=10
we minus 2x from both side which turns into
2y=-2x+10 (the variable always comes first)
Secon step is to divide 2 from the y to everything so 2y divided by 2 = y
-2 divided by 2 is -x and 2 divided by 10 is 5 and now you have the same equations which leads to infinite
y=-x+5

Answer:
204 men.
Step-by-step explanation:
Total number of workers in all the companies = 42 * 12.
