Question

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

Answer 1

Solution

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

$x=\frac{1.25+1.5y}{3.25}$

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

$13(\frac{1.25+1.5y}{3.25})-6y=10$

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
