Answer:
x=-2.25,y=-2.25
Step-by-step explanation:
The given system is

We want to solve the system for x and y that makes the system true.
Let us multiply the first equation by 3 while maintaining the second equation:

Subtract the current second equation from the first one.

Divide through by 12:

From the second equation we have:

This implies that:

1-2m-5m=15
combine like terms
1 -7m = 15
subtract 1 from each side
1-1-7m = 15-1
simplify
-7m = 14
divide by -7
-7m/-7 = 14/-7
simplify
m = -2
Answer:
50cm
Step-by-step explanation:
oh apdiya I just wanted to let you
3.7kg is also equal to 3700 grams
3700+620 grams
= 4320 grams
= 4320/1000 kg
= 4.32 kg
15% = 0.15
234.00 x 0.15 = 35.10
234.00 - 35.10 = 198.90
The camera will cost $198.90 after the discount.
