Answer:

$x= \frac{2046}{74}\\\\y = \frac{366234}{74}$

Step-by-step explanation:

$y = 179x\ ----- ( 1 ) \\\\y= 105x + 2046 \ ----- (2)\\\\$

$(1) => y - 179x = 0 \ ----- ( 3)\\\\(2) => y - 105x = 2046 \ ------ ( 4)$

$( 3 ) - ( 4) =>\\\\(-179x +105x ) = 0 - 2046\\\\-74x = -2046\\\\x = \frac{2046}{74}$

$Substitute \ x \ in ( 1 )\\\\y = 179x \\\\y = 179 \times \frac{2046}{74} = \frac{366234}{74}$
