I assume you mean this system.
Y - 4X = 10
Y = 2X - 6
You are given Y, so insert into top equation to find X.
(2X - 6) - 4X = 10
- 2X - 6 = 10
-2X = 16
X = - 8
===========find Y, bottom equation
Y = 2(- 8) - 6
Y = - 16 - 6
Y = - 22
============ You try checking it.

What type of system is 3x plus 2y equals 7 and -4x-3y equals 10?
They are simultaneous equations and their solutions are x = 41 and y = -58
How many solutions are there to the systems of equations?
I'm not 100% certain about what you're asking, but each function and relation can have different solutions, either one of the three ways. (Always dealing with two equations) This is based off my Grade 10 Knowledge One (Intersecting at one specific point) None (Parallel Lines) Coincident two lines with the same slope and intercept) Refer back to : " y=mx+b " equation if needed. If you are talking about the possible ways to find the solution (x,y), there are also three. Elimination, (Removing one variable to solve the equation) Substitution, (Knowing what x or y, and inputting in the second equation) Graphing, (By drawing both equations, This method is not very accurate)
What are the solutions of the simultaneous equations of x squared -xy -y squared equals -11 and 2x plus y equals 1?
1st equation: x^2 -xy -y squared = -11 2nd equation: 2x+y = 1 Combining the the two equations together gives: -x^2 +3x +10 = 0 Solving the above quadratic equation: x = 5 or x = -2 Solutions by substitution: (5, -9) and (-2, 5)
Why do unlike equations inequalities have more than one solution?
Precisely because of the inequality! Take the simplest case, of an equation or inequality that is already solved. For the equation, for example, take: x = 10 The equality means that x has to be 10, it can't be anything else. On the other hand, a similar inequality: x > 10 means that ANY number greater than 10 will do. For the sake of completeness, please note that more complicated equations can actually have more than one solution, too. For example: x2 = 25 has the solutions 5 and -5, while sin x = 0 has infinitely many solutions, since the sine function is periodic.
What are the solutions to the simultaneous equations of x square plus y square plus 4x plus 6y minus 40 equals 0 and x minus y equals 10?
Rearrange the second equation as x = 10+y and then substitute it into the first equation which will create a quadratic equation in the form of: 2y2+30y+100 = 0 and when solved y = -10 or y = -5 Therefore the solutions are: x = 0, y = -10 and x = 5, y = -5
What is the y-intercept of the line given by the question below Y4x-6?

What are the solutions to the simultaneous equations of x over 3 -y over 4 equals 0 and x over 2 plus 3y over 10 equals 27 over 5?
Simultaneous equations: x/3 -y/4 = 0 and x/2 +3y/10 = 27/5 Multiply all terms in the 1st by 12 and in the 2nd equation by 10 So: 4x -3y = 0 and 5x +3y = 54 Add both equations together: 9x = 54 => x = 6 Solutions by substitution: x = 6 and y = 8
Is (1 10) a solution to this system of equations?
No because there are no equations there to choose from.
How do you solve the system of equation x plus 2y-2 3x plus 4y6?
If you mean x+2y = -2 and 3x+4y = 6 then the solutions to the equations are x = 10 and y = -6
What are the solutions of the simultaneous equations of x squared -xy -y squared equals -11 and 2x plus y equals 1?
1st equation: x^2 -xy -y squared = -11 2nd equation: 2x+y = 1 Combining the the two equations together gives: -x^2 +3x +10 = 0 Solving the above quadratic equation: x = 5 or x = -2 Solutions by substitution: (5, -9) and (-2, 5)

How do you find the solutions of the simultaneous equations of 2x plus 5y equals 16 and -5x-2y equals 2 showing work in step by step stages?
1 If: 2x+5y = 16 and -5x-2y = 2 2 Then: 2*(2x+5y =16) and 5*(-5x-2y = 2) is equvalent to the above equations 3 Thus: 4x+10y = 32 and -25x-10y = 10 4 Adding both equations: -21x = 42 or x = -2 5 Solutions by substitution: x = -2 and y = 4

Does this system of equations have one solution no solutions or an infinite number of solutions 2x plus y equals 5 and 2y plus x equals 4?
One solution 2x+y =5 x+2y=4 multiply 1st eq by 2 rhen subtract: 4x+2y = 10 x + 2y = 4 3x = 6 x = 2 plug x into any of the above two equations and solve y = 1
