(-29/20, 31/20) (1/2, 2/5) no solution coincident Weegy: Solution: 10x - 10y = 1 x = y - 3 The second equation is solved for x, [ So substitute (y - 3) for x in the first equation 10x - 10y = 1 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. ] User: 5x - 2y = 6 x = 5 - y Solve the system of equations by substitution. (16/7, 19/7) (-4/3, 19/3) no solution coincident Weegy: (16/7, 19/7) is the answer. Letter A. User: x + y = 6 2x + y = 4 Solve the system of equations by substitution. (-2, 8) (2, -8) no solution coincident Weegy: A.(-2, 8) is the answer if we solve the system by substitution. User: 5x - 6 = y 2x - 3y = 4 Solve the system of equations by substitution. (-10/13, -128/13) (14/13, -8/13) no solution coincident Weegy: (14/13, -8/13) is the answer. Letter B. By substitution, we get the value of x as 14/13 while y is equal to -8/13. User: 7x - 2 = 2y 3x = 2y - 1 Solve the system of equations by substitution. (3/4, 13/8) (1/4, -1/8) no solution coincident Weegy: The system of equations 7x - 2 = 2y 3x = 2y - 1 is equals to: (3/4, 13/8). User: 8x = 2y + 5 3x = y + 7 Solve the system of equations by substitution. (-9/2, -41/2) (-1, -9/2) no solution coincident Weegy: The solution set of the equation 8x = 2y + 5 3x = y + 7 is {(-9/2, -41/2)}.

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 .
