Solve the system of equations. 4x + 4y + 3z = 6
4x + 7y + 5z = 5
5x + 3y + 32 = 7
a. (x = 2, y = 1,2 = -2)
b. (x = 4, y=-1,2 = 0)
C. (x = 3, y = 0,2=-3)
d. (x = 1, y = 2,2 =-1)
Please select the best answer from the choices provided

answer: slight chance that it will happen

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
