2y + x = 6 (equation 1)

x - y = -6 (equation 2)

Equation 1 - equation 2 we get: 3y = 12, so y = 4

2(4) + x = 6

Solve the equation: x = -2

The solution for the system of equations 2y + x = 6, x - y = -6 is (-2, 4)

x - y = -6 (equation 2)

Equation 1 - equation 2 we get: 3y = 12, so y = 4

2(4) + x = 6

Solve the equation: x = -2

The solution for the system of equations 2y + x = 6, x - y = -6 is (-2, 4)

Solve each system of equations. If possible, write your answer as an ordered pair.
y = -3x + 2
y = 4x - 5
**Weegy:** 4x + 12 = -3x - 6 + 4x, 4x + 12 = x - 6, 12 + 6 = x - 4x, 18 = -3x or -3x = 18, x = -6 (More)

y = -3x + 2

y = 4x - 5

replace y in the first equation we get:

4x - 5 = -3x + 2

4x + 3x = 2 + 5

7x = 7

x = 1

y = 4(1) - 5 = -1

The solution for the system of equations y = -3x + 2 y = 4x - 5 is (1, -1)

y = 4x - 5

replace y in the first equation we get:

4x - 5 = -3x + 2

4x + 3x = 2 + 5

7x = 7

x = 1

y = 4(1) - 5 = -1

The solution for the system of equations y = -3x + 2 y = 4x - 5 is (1, -1)

y = 5x - 3

y = 2x + 6

replace y in the first equation we get:

2x + 6 = 5x - 3

2x - 5x = -3 - 6

-3x = -9

x = 3

y = 5(3) - 3 = 15 - 3 = 12

The solution for the system of equations y = 5x - 3 y = 2x + 6 is (3, 12)

y = 2x + 6

replace y in the first equation we get:

2x + 6 = 5x - 3

2x - 5x = -3 - 6

-3x = -9

x = 3

y = 5(3) - 3 = 15 - 3 = 12

The solution for the system of equations y = 5x - 3 y = 2x + 6 is (3, 12)

x + y = 8

x + 3y = 14

the first equation - the second equation: 2y = 6

solve the equation: y = 3

x + 3 = 8, x = 5

The solution for the system of equations x + y = 8, x + 3y = 14 is (5, 3)

x + 3y = 14

the first equation - the second equation: 2y = 6

solve the equation: y = 3

x + 3 = 8, x = 5

The solution for the system of equations x + y = 8, x + 3y = 14 is (5, 3)

y = -2x + 6

y = 3x - 9

Replace y in the first equation:

3x - 9 = -2x + 6

5x = 15,

x = 3

y = -2(3) + 6 = 0

The solution for the system of equations y = -2x + 6 y = 3x - 9 is (3, 0)

y = 3x - 9

Replace y in the first equation:

3x - 9 = -2x + 6

5x = 15,

x = 3

y = -2(3) + 6 = 0

The solution for the system of equations y = -2x + 6 y = 3x - 9 is (3, 0)
