Question

Select the ordered pair from the choices below that is a solution to the following system of equations:

4y = 2x + 10

8x − 3y = -14
a) (-1, 2) b) (7, 6) c) (-3, 2) d) (5, 5)

Answer 1

since (-1, 2) satisfies both the given equations. therefore (-1, 2) is the corect ordered pair.

Answer 2

can you help me with this one too
Which of the following systems of equations has no solution?
9x + 5y = 1; 15y = 18x − 4
-7x − 7 = 3y; -14y − 8 = -6x
4x − 3y = 9; 6y = 8x − 18
7y = 5x − 10; 10x − 14y = 8

Answer 3

4x − 3y = 9; 6y = 8x − 18

Answer 4

can you help me on a few more please

Answer 5

just going to have dinner please

Answer 6

Select the ordered pair from the choices below that satisfies following system of equations:
2x − 10y = -14
-4y = -x − 5
(-1/2,1)
(-20, 3)
(3, 2)
(8, -4)

What would like help with?

Answer 9

help me with the question i just put the 2x − 10y = -14

Answer 10

2x − 10y = -14
-4y = -x − 5
Alrighty, first change the equations to x+y=b
2x-10y=-14
x-4y=-5
Multiply the second equation by -2.
2x-10y=-14
-2x+8y=10
Cancel the x, add the ys and constants.
-2y=-4
Divide by -2.
y=2
Take the y and plug it into an original equation to find x.
