Answer:

y = -13/14 and x = 240/7

Step-by-step explanation:

3x - 12y = 114 ............eqn 1

x + 38y = -1 ..........eqn 2

Multiply eqn 2 by 3

3x + 114 = -3

Subtract eqn 2 from 1

3x - 12y = 114

- 3x + 114 = -3

____________

0 - 126y = 117

y = 117/-126

y = -13/14

Sub y = -13/14 in eqn 1

3x - 12(-13/14) = 114

3x + 78/7 = 114

Multiply through by 7

21x + 78 = 798

21x = 798 - 78

21x = 720

x = 720/21

x = 240/7 = 34.29

Please help me with my Algebra homework!!!
balu736 [363]

Answer:

B) No Unique Solutions

Step-by-step explanation:

Given:

z=x+5y-14

-2y=-4\\y={-4}{-2}=2

3x+y-3z=14

now we now the value of y = 2 so we will substitute in equation  z=x+5y-14

z=x+5\times2-14\\z=x+10-14\\z= x-4

Now, We have value of y=2 and value of z=x-4 Substituting in both the value in equation 3x+y-3z=14

3x+2-3(x-4)=14\\3x+2-3x+12=14\\14=14

which means that the equation has Infinite solutions.
