Answer:
The solution to the system of equation are x=2, y=0, z=6
Step-by-step explanation:
System of equations
System of equations are equations that contains unknown variables.
Given the equations
3x+y+2z=8
8y+6z=36
12y+2z=12
From equation 2 and 3
8y+6z=36 * 1
12y+2z=12 * 3
______________
8y+6z=36
36y+6z= 36
Subtract
8y - 36y = 36 - 36
-28y =0
y = 0
Substitute y = 0 into equation 2
8(0)+6z=36
6z = 36
z = 6
From equation 1
3x+y+2z =8
3x + 0 + 2(6) = 8
3x = 8 - 12
3x = 6
x = 2
Answer:
9x-3x-4x=6x+4
2x=6x+4
2x-6x=4
-4x=4
x=-1
since you will divide bot sides by -4
Answer:
{-2, 8, -5, -2, 7}
Step-by-step explanation:
The domain is the set of input variables in a relation. In most cases, <em>x</em> represents the input variables, and <em>y</em> represents the output variables. Therefore, the domain is the set of numbers under the column <em>x</em>.
