Answer:
<em>* Substation :</em>
Subtract y from both sides of the equation.
x=6−y
x−y=4
Replace all occurrences of x with 6−y in each equation.
6−2y=4
x=6−y
Solve for y in the first equation.
y=1
x=6−y
Replace all occurrences of y with 1 in each equation.
x=5
y=1
The solution to the system is the complete set of ordered pairs that are valid solutions. (5,1)
The result can be shown in multiple forms. Point Form: (5,1)
Equation Form: x=5,y=1
<em>* Elimination :</em>
Multiply each equation by the value that makes the coefficients of x opposite.
x+y=6
(−1)⋅(x−y)=(−1)(4)
Simplify.
x+y=6
−x+y=−4
Add the two equations together to eliminate x from the system.
(x+y=6) + (−x+y=−4) = (2y=2)
Divide each term by 2 and simplify.
y=1
Substitute the value found for y into one of the original equations, then solve for x.
x=5
The solution to the independent system of equations can be represented as a point.
(5,1)
The result can be shown in multiple forms. Point Form:(5,1)
Equation Form: x=5,y=1

Answer:
Equation 5 + 2(3 + 2x) = x + 3(x + 1) has no solution.
Step-by-step explanation:
We are looking at two lines.
4(x + 3) + 2x = 6(x +2)
4x + 12 + 2x = 6x + 12
6x + 12 = 6x + 12
These are two identical lines, with an infinite number of solutions. (All points on the lines are the exactly the same).
5 + 2(3 + 2x) = x + 3(x + 1)
5 + 6 + 4x = x + 3x + 3
4x + 11 = 4x + 3
Both lines have the same gradient but have a different incline with the y axis. By definition, they are parallel to each other and there fore have zero solutions. Equation 5 + 2(3 + 2x) = x + 3(x + 1) has no solution, which is the answer we are looking for.
5(x + 3) + x = 4(x +3) + 3
5x + 15 + x = 4x + 12 + 3
6x + 15 = 4x + 15
These are two different lines with exactly one solution.
4 + 6(2 + x) = 2(3x + 8)
4 + 12 + 6x = 6x + 16
6x + 16 = 6x + 16
These are two identical lines, with an infinite number of solutions. (All points on the lines are the exactly the same).
