x=4y+1 x=4y-1 No,they have different solutions.
It works out that the solutions are: x = 3 and y = 2
Do you mean: 4x+7y = 47 and 5x-4y = -5 Then the solutions to the simultaneous equations are: x = 3 and y = 5
Each of these have an infinite number of solutions. Never can they be equal.
Do you want the solutions to the equations? If so then: x = 7 and y = 4
No.
The equation has infinitely many solutions.
the system of equations 3x-6y=20 and 2x-4y =3 is?Well its inconsistent.
x = 4y 3x - 2y = 20 Substituting the value of x into the second equation, 3*(4y) - 2y = 20 ie 12y - 2y = 20 or 10y = 20 so that y = 2 Then x = 4y = 4*2 = 8. So (x , y) = (8 , 2)
No.
Straight line equations:- And if: 3x-4y = 8 Then: y = 0.75x-2 whereas 0.75 or 3/4 is the slope and -2 is the y intercept
No, the two lines are parallel. If the lines are parallel they have no solution; if the lines are the same line then there are infinitely many solutions - all the points on the liens. 2x + 4y = 9 -4x - 8y = 4 The second equation can be divided through by -2 giving the equations: 2x + 4y = 9 2x + 4y = -2 Left of the equal signs (containing unknown x and y) are the same, but right of the equal signs (containing just numbers) are different. Thus the second line is parallel to the first line and they have no points in common and thus no solution.
