How is a system of 2 linear equations have no solution?
The pair of equations: x + y = 1 and x + y = 3 have no solution. If any ordered pair (x,y) satisfies the first equation it cannot satisfy the second, and conversely. The two equations are said to be inconsistent.
What is the solution system of equations of y-4x 1?
Since there are two variables involved ... 'x' and 'y' ... a solution requires two equations. That's why the collection of equations is called a "system" of them. So far, in your question, you have supplied one equation. We eagerly await the arrival of the second one, so that we may begin working on the solution.
What is the solution of x to the second power-5x equals 24?
x2-5x = 24 x2-5x-24 = 0 (x-8)(x+3) = 0 x = 8 or x -3
Is 8 a solution of x -1 or x 7?
It could be either, depending on what x equals. If x = 9, 8 will solve the first one. If x = 1, 8 will solve the second one.
What is the solution of the following linear system 12x plus 6y equals 9 4x plus 2y equals 0?
No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...

A chemist has one solution that is 80 percent acid and another solution that is 30 percent acid how much of the second 30 percent solution is needed to make a 400L that is 62 percent acid?
.80x+.30y=400*.62 .80x+.30y=248 This is equation one. x+y=400 x=400-y This is the second equation. .80(400-y)+.30y=248 320-.80y+.30y=248 -.50y=-72 Y=144 X=256 CHECK .80(256)+.30(144)=400(.62) 204.8+43.2=248 248=248
