Answer:
+-1,+-3,+-9,+-27,+-81
Step-by-step explanation:
T = 1/5(x - y + z)
First, let's get rid of the 1/5. To do this, you can multiply both sides by the reciprocal, or 5/1.
(5/1)T=[(5/1)1/5](x-y+z)
5T = x - y + z
Now subtract x from both sides.
5T - x = -y + z
Add y to both sides.
5T - x + y = z
So the answer is:
z = 5T - x + y
Using the substitution method, the solution to the system of linear equations, is: (6, 3).
<h3>System of Linear Equations</h3>
Using substitution method, we can make one of the variables the subject of the formula for one of the equations, then find the other variable by substituting.
Given:
- x + 4y = 18 --> eqn. 1
- y = -x+9 --> eqn. 2.
Substitute y = -x + 9 into equation 1.
x + 4(-x + 9) = 18
x - 4x + 36 = 18
-3x + 36 = 18
-3x = 18 - 36
-3x = -18
x = 6
Substitute x = 6 into equation 2 to find y
y = -6 + 9
y = 3
Therefore, using the substitution method, the solution to the system of linear equations, is: (6, 3).
