Answer:
(- 1, 2 )
Step-by-step explanation:
Given the 2 equations
- 3x - 5y = - 7 → (1)
- 4x + 5y = 14 → (2)
Add the 2 equations term by term to eliminate y , that is
- 7x + 0 = 7
- 7x = 7 ( divide both sides by - 7 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (1)
- 3(- 1) - 5y = - 7
3 - 5y = - 7 ( subtract 3 from both sides )
- 5y = - 10 ( divide both sides by - 5 )
y = 2
solution is (- 1, 2 )

Answer:
$628.67
Step-by-step explanation:
15% of her restaurant bill is $94.30.
15 goes into 100, 6 2/3 times. so we multiply both 15% and $94.30 by 6 2/3 to get 100% and the restaurant bill.
15% x 6 2/3 = 100%
$94.30 x 6 2/3 =
628.666666
or
$628.67
I hope that this helps! :)
