6 0

x - y = 3

x = 3 + y

x -3 = y

y = x-3

put it in 1st equation

2x +y = 15

2x + x - 3 = 15

3x - 3 = 15

3x = 15+3 = 18

x = 18/3 = 6

x = 6

How do we get .375 into a percent
inessss [21]
You turn it into a percent by multiplying by 100 because a percent means out of a hundred so that's how you do it.  You just multiply the decimal by 100.
