(3x - 1)^2 = 5

3x - 1 = 5^1/2

3x = 5^1/2 + 1

x = (5^1/2)/3 + 1/3

x - y = 4

x + y = 2

adding up equations the result is 2x = 6

x = 6/2 = 3

3 - y = 4

y = 3 - 4 = -1

the solution for the system x - y = 4 x + y = 2 is (3, -1)

x + y = 2

adding up equations the result is 2x = 6

x = 6/2 = 3

3 - y = 4

y = 3 - 4 = -1

the solution for the system x - y = 4 x + y = 2 is (3, -1)

y = 2x + 3

2y = 4x + 6

substitute y in the second equation the result is:

2(2x + 3) = 4x + 6

4x + 6 = 4x + 6

4x - 4x = 6 - 6

0 = 0

the system of equations y = 2x + 3 2y = 4x + 6 has infinite solutions.

2y = 4x + 6

substitute y in the second equation the result is:

2(2x + 3) = 4x + 6

4x + 6 = 4x + 6

4x - 4x = 6 - 6

0 = 0

the system of equations y = 2x + 3 2y = 4x + 6 has infinite solutions.

For the following system, x + 5y - 10 = 0 x = 2y - 8, use the second equation to make a substitution for x in the first equation. The resulting equation is: 2y - 8 + 5y - 10 = 0, it is 7y - 18 = 0 in simplest form.

x + y = 0

x - y + 2 = 0

adding up equations the result is:

2x + 2 = 0

2x = -2

x = -2/2 = -1

y = -x = -(-1) = 1

The solution for the system x + y = 0 x - y + 2 = 0 is (-1, 1)

x - y + 2 = 0

adding up equations the result is:

2x + 2 = 0

2x = -2

x = -2/2 = -1

y = -x = -(-1) = 1

The solution for the system x + y = 0 x - y + 2 = 0 is (-1, 1)

y - 4 = 0

y = 4;

2x - (4) - 2 = 0

2x = 6

x = 6/2 = 3

the solution for the system y - 4 = 0 2x - y - 2 = 0 is (3, 4)

y = 4;

2x - (4) - 2 = 0
