Solve for x and y 4x+ 5y = 10, 6x - 5y = 5.

Expert Answers

An illustration of the letter 'A' in a speech bubbles

4x + 5y = 10.......(1)

6x -5y = 5...........(2)

Using the elimination method, add (1) and (2):

==> 10x = 15

==> x = 15/10 = 3/2

==> x= 3/2

Now to calculate y, let us substitute with (2):

6x - 5y = 5

6(3/2) - 5y = 5

==> 5y = 9 - 5

==> 5y = 4

==> y= 4/5
