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)
Answer:
B and D are the answer's.
Step-by-step explanation:
Well you want 100% + 3.2% = 103.2%
103.2% = 103.2/100= 1.032
Answer:
x=4
Step-by-step explanation:
4x=8x-16
(plus both sides by 16 and minus both sides by 4x)
16=4x
(divide 16 by 4 )
x=4
