what is the answer? show work

The answer is 42.

Step-by-step explanation:

First, according to order of operations, we will start with the exponents and parenthesis.

4(3+8)-8^2/32 | Solving (3 + 8) and 8^2

4(11)-64/32 | Now we multiply and divide.

44-64/32 |

44-2 | Now we just subtract

42

the answer is 62

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
