(2,-2) is a solution to the system of equations.
9x = 10 – 4y
y = 3x – 8

yes ! (2,-2) is a solution to the system of equations

Step-by-step explanation:

9x = 10 – 4y

9(2) = 10 - 4(-2)

18 = 10 + 8

18 = 18

y = 3x - 8

- 2 = 3(2) - 8

- 2 = 6 - 8

- 2 = - 2

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.
