Answer:x=2, y=3
Step-by-step explanation:
solving this equation simultaneously
-9x - 2y=-12.............(1)
2x + 5y=-11.. ...........(2)
Using elimination method
Multiply equation 2 by 2 and equation 1 by 5
-45x -10y= -60...........(3)
4x + 10y=-22...............(4)
Subtracting equation 2 from 1
-41x + 0=-82
41x=82
x=82/41
X=2
To find y put x in equation 1
-9x - 2y= -12
-9(2)-2y=-12
-18-2y=-12
-2y=-12+18
-2y=6
Y= 6/2
Y=3
X=2, Y=3
y = -3.7x + 1 when x = -2
Plug in:
y = -3.7(-2) + 1
-3.7(-2) = 7.4
y = 7.4 + 1
7.4 + 1 = 8.4
y = 8.4
Answer - C) 8.4

Answer:
one spent $3,800 and the other spent $5,700
Step-by-step explanation:
first add the 3 and 2 so you get 5 then divide 9,500 into 5 which is 1900 then multiply that by 2 which is 3800 now we know one man spent $3800 then we do the same thing with 3 so we take 1900 and multiply it by three which is $5700
your answer is that one man spent $3,800 and the other spent $5,700
