Question

In 4-6 solve each system using substitution3.25 x -1.5 y = 1.2513x -6y= 10

Answer 1

We have the following system of equations:

3.25x - 1.5 y= 1.25 (1)

13x -6y= 10 (2)

We can solve for x in the first equation and we got

`x=(1.25+1.5y)/(3.25)`

We can replace this into the second equation and we got:

`13((1.25+1.5y)/(3.25))-6y=10`

Then we can solve for y on this way:

`5+6y-6y=10`

Since 5 is not equal to 10 then we can conclude that this system of equations has no solution
