Question

5x+2y= 5
3х - у= 14
Solve

Answer 1

x = 3

y = -5

Step-by-step explanation:

5x+2y= 5 equation 1

3х - у = 14 equation 2

using equation 2 we have:

3x - 14 = y equation 3

using equation 3 in equation 1 we have:

5x + 2(3x -14) = 5

5x + 6x -28 = 5

11x = 5+28

11x = 33

x =33/11

x = 3

using equation 3 we have:

3(3) - 14 = y

y =9-14

y = -5

Explanation:

Answer 2

x = 3

y = -5

Explanation:

5x+2y= 5 equation 1

3х - у = 14 equation 2

using equation 2 we have:

3x - 14 = y equation 3

using equation 3 in equation 1 we have:

5x + 2(3x -14) = 5

5x + 6x -28 = 5

11x = 5+28

11x = 33

x =33/11

x = 3

using equation 3 we have:

3(3) - 14 = y

y =9-14

y = -5
