1) x = - 4, y = - 12; (- 4, - 12)
2) x = 34, y = 17; (34, 17)
3) x = 16, y = 7; (16, 7)
4) x = 7, y = - 4; (7, - 4)
5) x = - 4, y = 10; (- 4, 10)
6) x = 12, y = - 7; (12, - 7)
7) x = 5, y = 10; (5, 10)
8) x = 11, y = - 12; (11, - 12)
Answer:
<u>a= -4</u>
Step-by-step explanation:
subtract 4a from both sides
add 15 to both sides
divide both sides by -3
(order of operations)
With Fractions? For example in 1/2 divided by 2/3 what you do is you leave the first fraction alone so it stays 1/2, then you change the sign from divide to multiply so it becomes 1/2 x by and then you take the next fraction and flip it upside down so 2/3 becomes 3/2. So 1/2 divided by 2/3 becomes 1/2 x 3/2. Only works with divisions
