User: 3x - 4y = 7 3x + 2y = -5 When the second equation is subtracted from the first, the resulting equation is _____.

Weegy: -6y = 12

User: 7x - 3y = 4 2x - 4y = 1 Which of the following systems is not the same as solving the system shown? 28x - 12y = 16 and -6x + 12y = -3 14x - 6y = 4 and -14x + 28y = 1 -28x + 12y = -16 and 28x - 56y = 14

Weegy: (28x - 12y = 16 and -6x 12y = -3) is not the same as solving the system.

User: 2x + 3y = 6 5x + 2y = 4 Which of the following equations could be the result of multiplication and addition to eliminate a variable in the system of equations?

Weegy: c. 11y = 22
shifa saleheen|Points 9966|

User: 5x + y = 6 5x + 3y = -4 The y-coordinate of the solution to the system shown is _____.

Weegy: that would be -5
yestfl|Points 1444|

User: x + y = k x - y = k The solution to the system shown is _____.

Weegy: Let's use the reduction method by adding them up, you'll cancel out the y's, leaving you with x=k Now if x=k, let's replace k by x x-y=k x-y=x x-x=y 0=y Since x = k and 0 = y, [ we'll say that the solution to this system is (K,0) ]

7x - 3y = 4 multiple 4 on both sides 28x - 12y = 16
2x - 4y = 1 multiple 3 on both sides 6x - 12y = 3
Subtract the new equations 22x = 13, so x = 13/22
7(13/22) - 3y = 4
91/22 - 4 = 3y
3y = 3/22
y = 1/22
7x - 3y = 4 2x - 4y = 1 The solution to the system of equations is (13/22, 1/22)
