3(14-5)
using distributive property

27

Step-by-step explanation:

The distributive property is simple. When there are numbers inside the parenthesis and a number outside of it like in the equation, you multiply all of the numbers inside the parenthesis by the outside number.

3 ( 14 - 5 )

3 * 14 = 42

3 * -5 = -15

After this, you take the remaining numbers and use the method PEMDAS to solve the equation.

42 - 15 = 27

Your answer is 27, hope this helps :)

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
