What is the result of subtracting the second equation from the first?
-4x-2y=-2
x-2y=9

Answer 1

Given:

• -4x - 2y = -2
• x - 2y = 9

Subtracting:

• -4x - 2y - (x - 2y) = -2 - 9
• -4x - 2y - x + 2y = - 11
• -5x = -11
• 5x = 11
• x = 11/5
• x = 2.2

You can now find y:

• 2.2 - 2y = 9
• 2y = 2.2 - 9
• 2y = - 6.8
• y = -6.8/2
• y = -3.4

Solution (2.2, -3.4)
