The difference of twice a number k and 8 is 12
laiz [17]

Answer:

k = 10

Step-by-step explanation:

Difference means subtract.

2k - 8 = 12

is how that statement is translated.

Add 8 to both sides.

2k - 8 + 8 = 12 + 8

2k = 20                    

Divide by 2

2k/2 = 20/2

k = 10

1. If you are asked to use elimination to solve for x", what do you need to multiply the bottom equation by to eliminate "y?
hram777 [196]

Answer:

-5

Step-by-step explanation:

There is different ways to solve methods of elimination but if you wanted to cancel y out you would multiply by the opposite sign....for example

7x + 5y = 19

-5 (2x + y = 19) ---> -10x -5y = 95

this would cancel out your y to solve for x so you can plug it back in and solve! hope this helps!!!
