What is the ordered pair of 4x-7y equals -23 8x plus 5y equals 49?
The lines intersect at (3, 5)
What is the ordered pair of 3x minus 8y equals -18 and 2x plus 5y equals 19?
- 2(3X - 8Y = - 18)3(2X + 5Y = 19)- 6X + 16Y = 366X + 15Y = 57----------------------------add31Y = 93Y = 3========now, find X; second equation will do2X + 5(3) = 192X + 15 = 192X = 4X = 2==========both check and are consistent(2, 3)-----------------ordered pair
What is the ordered pair to -3y equals x-5 and x plus 5y equals 7?
x = 2 and y =1 so the lines intersect at (2, 1)
What does -8 minus 5y equals 12 minus 9y equal?
-8-5y = 12-9y 9y-5y - 12+8 4y = 20 y = 5
What is Y when 5y times 3y minus 1 equals to -15?
Y=-1
Solve the following system of equations express your answer as an ordered pair 2x plus 5y equals 16 and -5x minus 2y equals 2?
The solutions are: x = -2 and y = 4
What is the ordered pair the is th solution to these equations x equals 5y and 2x - 3y equals 14?
(10, 2)
What is the ordered pair of 4x-7y equals -23 8x plus 5y equals 49?
The lines intersect at (3, 5)
What is the ordered pair to 2x-5y equals -1?
The equation 2x-5y=-1 has a graph that is a line. Every point on that line is an ordered pair that is a solution to the equation. So pick any real number x and plug it in. You will find a y and that pair (x,y) is an ordered pair that is a solution to this equation. For example, let x=0 Then we have -5y=-1so y=1/5 The ordered pair (0, 1/5) is a point on the line and a solution to the equation.

What is the ordered pair that is the solution to these equations 3x - 2y equals 8 2x plus 5y equals -1?
y=(-1) x=(2)
3x plus 5y equals 48 -3x plus 5y equals 12Solve the system of equations Enter your answer as an ordered pair?
3x+5y=48 5y=48-3x-3x+5y=12 -3x+(48-3x)=12-6x=-36x=65y=48-3(6)5y=30y=6(6,6)
What is the ordered pair to -3y equals x-5 and x plus 5y equals 7?
x = 2 and y =1 so the lines intersect at (2, 1)
What is the ordered pair for 2x plus 5y equals 16 plus -5x minus 2y equals 2?
2x + 5y = 16 + (-5x) - 2y = 2 That gives 2x + 5y = 2 . . . . . . . . . . (I) and -5x - 2y = - 14 or 5x + 2y = 14 . . . . (II) (I)*5: 10x + 25y = 10 (II)*2: 10x + 4y = 28 Subtracting the second from the first, 21y = -18 so y = -18/21 = -6/7 and then by (I) x = 1 - 5y/2 = 1 - 5/2*(-6/7) = 1 + 15/7 = 22/7 So the ordered pair is (22/7, -6/7)
Which ordered pair is on the graph of the equation 2x 5y 4?
Without an equality sign and not knowing the plus or minus values of the given terms it can't be considered to be an equation.
What does -8 minus 5y equals 12 minus 9y equal?
-8-5y = 12-9y 9y-5y - 12+8 4y = 20 y = 5
How do you factor out 5y minus 20 equals?
5(y-4)
