x + 4y = -14 eqn1
2x + 3y = 13 eqn2
Using the elimination method we multiply eqn1 by 2
2x + 8y = -28 eqn1b
Subtract eqn2 from eqn1b
2x + 8y = -28 eqn1b
2x + 3y = 13 eqn2
5y =-41
y = -8 and 1/5
substituting this into eqn1 we get
x +4 (-41/5) = -14
x = (14*5) / (41 *4)
x = (35/82)

How do you solve this problem -3x plus 2y equals 1 in elimination?
The elimination method only works with simultaneous equations, hence another equation is needed here for it to be solvable.

z=pq
Y equals x plus 3 and 3x-y equals 5?
Solve this simultaneous equation using the elimination method after rearraging these equations in the form of: 3x-y = 5 -x+y = 3 Add both equations together: 2x = 8 => x = 4 Substitute the value of x into the original equations to find the value of y: So: x = 4 and y = 7
Solve y equals -2 4x-3y equals 18?
y = -24x - 3y = 18 (use the substitution method)4x - 3y = 18 (substitute -2 for y, and solve for x))4x - 3(-2) = 184x + 6 = 18 (subtract 6 to both sides)4x = 12 (divide by 2 to both sides)x = 3Thus, (3, -2) is the solution of the given system of equations.
Solve the system by the elimination method 7x-9y equals 35 plus -3x plus 6yequals -15?
7x - 9y = 35-3x + 6y = -15 (divide the second equation by 3, after that multiply it by 7)7x - 9y = 35-7x + 14y = -35 (add both equations)5y = 0 (divide both sides by 5)y = 07x - 9y = 35 (substitute 0 for y)7x = 35 (divide both sides by 7)x = 5Thus the solution of the given system of the equations is x = 5 and y = 0.
