Answer:

-9

Step by step explanation:

it can also be written as; 18 over x is equal to -2 over 1

you cross multiply to get 18 = -2x

then multiply through with -2; 18 over -2 = -2x over -2

you cross out; -2 cancels itself and -2 goes into 18 , -9 times

Therefore; the answer is -9

Two numbers have a sum of 33. The same two numbers have a difference of 13. What are the two numbers?
padilas [110]

Answer:

x = 23

y = 10

Step-by-step explanation:

Let the two numbers be x and y where x>y

x + y = 33

<u>x - y  = 13</u>             Add

2x = 46               Divide by 2

2x/2=46/2           Do the division

x = 23

=============

Solve for y

x + y = 33               Substitute for x

23 + y = 33             Subtract 23 from both sides.

23-23+y = 33 - 23  

y = 10
