Question

Which ordered pair is a solution to the system of equations?

Answer 1

Answer:

• See below

Step-by-step explanation:

Given system:

• 2x - y = - 2
• 15x - 2y = - 7

Solve by elimination, multiply the first equation by - 2 and add up the equations:

• -2(2x - y) + 15x - 2y = - 2(- 2) - 7
• -4x + 2y + 15x - 2y = 4 - 7
• 11x = - 3
• x = - 3/11

Find the value of y:

• 2( - 3/11) - y = - 2
• -6/11 - y = - 2
• y = 2 - 6/11
• y = 1/11

Solution is:

• ( - 3/11, 1/11)

• None of the answer choices is matching this solution. Something must be wrong with the given equations.
