algebra help pls i dont get thiis

Answer 1

Answer:

4 and -7

Step-by-step explanation:

Okay, so let's try the first one: jk/j + k.

Now, what is j equal to? It says that j means 6. What is k equal to? K means 12.

Therefore, just replace the j and k with the numbers provided:

j = 6

k = 12

6(12)/6 + 12 = 72/6 + 12 = 72/18 = 4.

Therefore your first answer is 4.

Next one is x + y/y - x

x = 4

y = 3

Substitute the variables with the numbers provided:

4 + 3/3 - 4

7/-1

= -7

Answer 2

Answer:

$(6 \times 12) \div (6 + 12) = 72 \div 18 = 4$

$(4 + 3) \div (3 - 4) = 7 \div - 1 = - 7$
