Answer:
5.4
Answer: The value of x rounded to the nearest tenth is 5.4.
Step-by-step explanation:
Answer:
x=1, y=-1. (1, -1)
Step-by-step explanation:
2x-3y=5
x+2y=-1
---------------
2x-3y=5
-2(x+2y)=-2(-1)
-----------------------
2x-3y=5
-2x-4y=2
-------------
-7y=7
y=7/-7
y=-1
x+2(-1)=-1
x-2=-1
x=-1+2
x=1
Let shirts be x and ties be y
3x+5y=$60 Equation 1 (Equation 1 will be denoted by *)
2x+3y=$39 Equation 2 (Equation 2 will be denoted by !)
*x2 6x + 10y = $120
!x3 6x + 9y = $117
*-! y = 120-117 =3
Ties are $3 each
Substitute this value back into one of the original 2 equations:
3x+5y=$60
3x+(5x3) = 60
3x+15=60
3x=45
x=15
Shirts are $15
