-6x +5y=1
6x+4y=-10
i need to know what x and y is. these two equations are with the same problem.
6x+4y=-10

Just add the equations to get
9y=-9 so y=-1
Substitute y=-1 into either equation and solve for x,
6x + 4(-1) = -10
6x -4 = -10
6x = -6
x = -1
Ans: x=-1, y=-1
9y=-9 so y=-1
Substitute y=-1 into either equation and solve for x,
6x + 4(-1) = -10
6x -4 = -10
6x = -6
x = -1
Ans: x=-1, y=-1
-
-6x + 5y = 1
6x +4y= -10
(add these two equations the 6x cancels with -6x and get:)
9y= -9
divide both sides by 9 to isolate y and get:
y= -1
plug in -1 for y into any of the two equations to find x I picked the first one:
-6x +5(-1) =1
-6x - 5=1
(add 5 and get)
-6x =6
divide by -6 and get:
x= -1
therefore
x and y = -1
6x +4y= -10
(add these two equations the 6x cancels with -6x and get:)
9y= -9
divide both sides by 9 to isolate y and get:
y= -1
plug in -1 for y into any of the two equations to find x I picked the first one:
-6x +5(-1) =1
-6x - 5=1
(add 5 and get)
-6x =6
divide by -6 and get:
x= -1
therefore
x and y = -1
-
y=-1
x=-1
x=-1
