Answer:
The solution is (3, -3)
Step-by-step explanation:
5x + 2y = 9
2x - 3y = 15
Use elimination by addition/subtraction. Multiply the first equation by 3 and the second by 2, obtaining:
15x + 6y = 27
4x - 6y = 30
----------------------
19x = 57
This yields x = 3.
Substituting 3 for x into 5x + 2y = 9, we get 5(3) + 2y = 9, or
15 + 2y = 9, or
2y = -6
This yields y = -3.
The solution is (3, -3)
The answer is going to be 7
to make 4 and 2/3 a fraction you multiply 4 times 3, and then add two, so it will com in as 14/3
then you take the multiplicative inverse of that fraction which would make is 3/14, and then you multiply it by 2/3
3*2=6
14*3=42
so it comes out as 6/42, then you take the multiplicative inverse of that, and it come in at 42/6, divide 6 into 42 and you get seven.
hope this helps
-2 by -3 good luck on what ever your working on
