a^2·a^-3·a

= a^2*a*^-3

= a^3*a^-3

= a^3*1/a^3

= 1

= a^2*a*^-3

= a^3*a^-3

= a^3*1/a^3

= 1

The second equation is solved for x, [ So
substitute (y - 3) for x in the first equation

10(y - 3) - 10y = 1
10y - 30 - 10y = 1
-30 = 1
They y's all canceled out and left a false numerical equation,
-30 is not equal to 1, so there is no solution. The system is called an
inconsistent system of equation.

There no solution for x - y = 6 , x = y + 2 Solve the system of equations by substitution.

Put equaiton 2 in euqation 1 , we get the result as follows:

x - y = 6 ,

y + 2 - y = 6 ,

2 = 6 ,

2 is can't be equal to 6 ,

So it has no solution .

The solution for 8y - 1 = x , 3x = 2y is (1/11, 3/22) .Solve the system of equations by substitution.

put equation 1 of x = 8y - 1 in equation 2 ;

3(8y - 1) = 2y ;

24y - 3 = 2y ;

22y = 3 ;

y = 3/22 ;

x = 8*3/22 - 1 ;

x = 24/22 - 22/22 ;

x = 2/22 ;

x = 1/11 .

The equations 2x - y = c , x + 2y = d are intersecting .

The slope of 2x - y = c is 2 , the slope of x + 2y = d is -1/2 , so 2 lines are perpendicular to each other ,so they are intersecting .
