Question

Which is the best approximation for the solution of the system of equations?y=-2/5x+1y=3x-2

Answer 1

We have the following system of equations:

y = -2/5x + 1

y = 3x -2

We can replace the seocnd equation in the first oen and we got:

3x -2 = -2/5x +1

And solving for x we got:

17/5x = 2+1

17/5x = 3

x= 15/17

And solving for y we got:

y= 3*(15/17) -2= 11/17
