eq^2: 7x=84 divide 84 by 7 which is 12.
therefore x is equal to 12. Then
1) take that 12 you got in equation 2 and substitute in equation 1 which is:
7x-12y=180
7(12)-12y=180
84 -12y=180
-12y=180-84
-12y=96 ............divide both sides with -12
-y=8 (×-1) both sides
y= -8
therefore 7(12)-12(-8)=180
16.76 rounds off to 17
After the dot if it’s 1-4 then they it would’ve been 15
5-9 is 17

Answer:
The product of (-4)(7) is -28
Step-by-step explanation:
First you will multiply the number together.
This gets you -28.
The reason it is a negative number is because when you multiply a positive and a negative number together, you get a negative number.
Whereas, if it were two negative numbers, (-4)(-7), or two positive numbers,
(4)(7), the answer would have been positive, 28.
