What is the solution of the following system of equations 3y - 2x equals 3 y equals x?
x = y = 3
-2X plus 3Y equals 8?
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
What is the solution of the system of equations 2x-5y equals 11and -2x plus 3y equals -9?
2X - 5Y = 11 - 2X + 3Y = - 9 ----------------------just add 2Y = 2 Y = 1 --------------now, insert into one of the equations to find X 2X - 5(1) = 11 2X - 5 = 11 2X = 16 X = 8 ----------------check in both equations 2(8) - 5(1) = 11 16 - 5 = 11 11 = 11 ----------------one checked - 2(8) + 3(1) = - 9 - 16 + 3 = - 9 - 13 does not equal - 9 ---------------------------------an inconsistent system; check with substitution on bottom equation - 2X + 3Y = - 9 - 2X = - 3Y - 9 X = 3/2Y + 9/2 ---------------------insert back into both equations, bottom first - 2(3/2Y + 9/2) = - 9 -3Y - 9 = - 9 obviously this is inconstant and leads to Y = 0 -----------------------------------------------------------------no need to try top, this system is inconsistent.
Solve the system of equations 3x - y 4z 9 2x 3y - 2z 16 4x - 3y z 1?
post an equation first.
What type of lines match these equations 3x plus 2y -5 -2x plus 3y -5?
If you mean 3x+2y = -5 and -2x+3y = -5 then they are straight line equations
What is the solution to this system of equations 6x-3y -33 2x y -1 using substituition?
If you mean: 6x-3y = -33 and 2x+y = -1 Then solving the simultaneous equations by substitution: x = -3 and y = 5
What is the solution of the following system of equations 3y - 2x equals 3 y equals x?
x = y = 3
Is 2x-y equals 15 and 2x plus 3y equals -21 consistent or inconsistent?
2x - y = 15 2x + 3y = -21 As you observe both equations (having different slopes), you see that the system is consistent, and it has only one solution.
What is the solution to the following system of equations 2x minus 3y equals 4 and 4x plus y equals -6?
{-1,-2}
Is (-5 -1) a solution to this system of equations 3y -2x and ndash 13 -4x -8y plus 12?
Without any equality signs the given terms can't be considered to be equations.
Examples of linear equations in two variables?

Type the ordered pair that is the solution to these equations.2x - 3y = 7-3x + y = 7?
(-4,-5)
What is the ordered pair the is th solution to these equations x equals 5y and 2x - 3y equals 14?
(10, 2)
-2X plus 3Y equals 8?
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
What is the solution of the system 2x plus 3y equals 2 and 4x plus 6y equals 4?
That system of equations has no solution. When the two equations are graphed, they turn out to be the same straight line, so there's no such thing as a single point where the two lines intersect. There are an infinite number of points that satisfy both equations.
