Two times a number minus four times another number is ten, and four times the first number minus four times the second number results in four. What are the two
numbers? Let the first number be x. Iand the second number be y.

-3 and -4

Step-by-step explanation:

x = 1st number

y = 2nd number

2x-4y=10

4x-4y=4

distribute first equation by -2 to eliminate x-values:

 -4x + 8y = -20

+ 4x - 4y = 4

4y = -16

y = -4

solve for 'x':

2x - 4(-4) = 10

2x + 16 = 10

2x = -6

x = -3

true !

step-by-step explanation:

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
