Answer 2

Answer:

The solution of given equations are (-9300,11200).

Step-by-step explanation:

The given equations are

$x+y=1900$                           .... (1)

$\frac{x}{60}+\frac{y}{70}=5$

Simplify the second equation.

$\frac{7x+6y}{420}=5$

$7x+6y=2100$                       ..... (2)

From equation (1) and (2) we get

$7x+6(1900-x)=2100$

$7x+6(1900-x)=2100$

$7x+11400-6x=2100$

$x=-9300$

Substitute x=-9300 in equation (1).

$-9300+y=1900$

$y=11200$

Therefore the solution of given equations are (-9300,11200).
