4x-8-2 can be more easily written as 4x-10. The solution to this equation would be 5/2
(0, -14)
There can be no solution since there is no equation (nor inequality) in the question.
x2 + 2y - 6x + 8y - 1 = x2 - y2 + 4x + 6y - 1 y2 - 10x + 4y = 0 y(y+4) = 10x It cannot be solved completely because with two variables (x and y) you need two independent equations for a full solution.
This is a simultaneous equation question. 4x-4y = -40 4x+43 = y Rearrange the second equation so that all the letters and numbers are in line with the first equation remembering to alter the values of the + and - signs. 4x-4y = -40 4x-y = -43 Subtract the second equation from the first equation remembering that a - - is equal to a + This will leave you with -3y = 3 and by dividing both sides by -3 gives you y = -1 Therefore the solution of the simultaneous equation is x = -11 and y = -1. Substitute these values into the original equations to make sure that your solution is correct.
4x-y2 = 2
4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
4x-8-2 can be more easily written as 4x-10. The solution to this equation would be 5/2
4x-y2=2xy 2x ? y5 if its plus its 7 xy

-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
If: 4x = x+15 Then: x = 5
Without an equality sign it can't be considered to be an equation and so therefore it has no solution.
Yes, because the equation is linear, there is only one solution:4x - 3 = 12 +2x4x - 2x = 12 + 32x = 15x = 7.5There is no other solution
There can be no solution since there is no equation (nor inequality) in the question.
The answer is (-8,8)
It has no solution and if you mean 4x+10+3x+40-3x then it can be simplified to: 50+4x _________________________________________________________________________________________ Assuming that the equation is 4x+10+3x+40-3x = 0, then it will reduces to 4x = - 50, then the answer is: x = -12.5
