Which system of equations matches this situation?

Four times one number added to another number is 36. Three times the first number minus the other number is 20. Find the numbers

• 4x - y = 36

  3x + y = 20

• 4xy = 36

  -3xy = 20

• 4x + x = 36

  3y - y = 20

• 4x + y = 36

  3x - y = 20

Solve for Y

4x + 2y = 10

• y = 2x + 5

• y = -2x + 10

• y = 2x + 10

• y = -2x + 5

Solve for X

x - 4 = 6x + 26
