Question

Tell whether the system has one​ solution, infinitely many​ solutions, or no solution.

Answer 1

B. The system has no solution.

Explanation:

[12x + 7y] = (20)

[12x + 7y] = (11)

The numbers in (parentheses) are both different while the numbers in the [brackets] are the same.

Answer 2

20=7y+12x

• 7y=-12x+20
• y=-12/7x+20/7

12x+7y=11

• 7y=-12x+11
• y=-12/7x+11/7

Slopes are

• Lines are parallel

No solutions
