We can use the distributive property to set up an expression that is equal to this problem.
14 times 8 is 112
14 times -6 is -84x
14 times 12 is 168
(If you don't know the distributive property ask and I can explain it)
We can combine that together to get:
112 +168 -84x
Or, condense it further:
280-84x is equivalent to 14(8-6x+12)
I Hope That I Am Not To Late, But The Answer Is D (7,4) <3
<u>Explanation </u>
2 x 7 = 14
5 x 4 = 20
14-20= -6
>>>
2 x 7= 14
7 x 4 = 28
14-28= -14
X= 7 & Y=4
Once again sorry if i am late, if others come I hope this helps UwU
