Answer:

26=x

Step-by-step explanation:

well you need to do the distributive property.

-3(x-2) = -6x+6

9(x+8) = 9x+72

-6x+6=9x+72

now you subtract -6x from -6x and 9x

and add 72 to 6

-6x +6 =9x + 72

-6x + 72 -6x -72

78=3x

divide them both by 3

26=x

What that two numbers when multiplied give 600 and when added give 59

ozzi

Answer:

Step-by-step explanation:

Let the 2 numbers be x and y

From the problem we have that

x * y = 600 and x + y = 59

From x + y = 59 -> x = 59 - y

Plug x = 59 - y to x * y = 600 we have

(59 - y) * y = 600

-> 59y - y^2 = 600

-> -y^2 + 59y - 600 = 0

-> y = $(59 - \sqrt{1081})/2$ or $(59 + \sqrt{1081})/2$

Then we could plug the answers in and find x because x = 59 - y
