Solve the following simulataneous equations using an algebraic method (not graphical). 2x + 5y = 0
3x-4y = 23

Given:

The equations are

To find:

The solution of given system of equations.

Solution:

We have,

       ...(i)

      ...(ii)

From (i), we get

       ...(iii)

Putting this value in (ii), we get

Putting y=-2 in (iii), we get

Therefore, the solution of given system of equation is (5,-2).

rounding to the nearest thousandth would be 452,000
