When did the caste system evolve into a four tiered hierarchy?A.) when the Aryans ruled over the region - They arrived in 1500BC and developed the grouping of people based on their status and activities in life.
The Depression left some workers without paying jobs or the ones who had kept jobs got low wages and got cutbacks in hours
Substitute y= 2x - 4 into 7x - 5y = 14.
> 7x - 5(2x - 4) = 14
> 7x - 10x + 20 = 14
> -3x = -6
> x = 2
Now sub x = 2 back into y= 2x - 4 to find what y equals.
> y = 2(2) - 4
> y = 4 - 4
> y = 0
Therefore, x = 2 and y = 0.
