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

Can i get brainliest?
Answer:
No, because substituting the given ordered pair doesn't yields two true expressions
Step-by-step explanation:
5x + y = 8
5 + 3 = 8 so thats correct
x + 2y = 5
1 + 6 =7, not 5
so only 1 is correct
Answer:
x > 6
Step-by-step explanation:
Given
3(x + 4) - 5(x - 1) < 5 ← distribute and simplify left side
3x + 12 - 5x + 5 < 5
- 2x + 17 < 5 ( subtract 17 from both sides )
- 2x < - 12
Divide both sides by - 2, reversing the symbol as a result of dividing by a negative value.
x > 6
