If a worker makes 600,000 a month, we can multiply that to 12, since there are 12 months in a year. 600,000 x 12 = 72,000,00, so the worker makes $72,000,00 a year. :)
10x+3y=43
-9x-y=-20
From second equation,
y=-9x+20
Substitute third equation into first equation,
10x+3(-9x+20)=43
10x-27x+60=43
-17x=43-60
-17x=-17
x=1
y= -9+20= 11
