Question

Use substitution to solve the system of equations.

How many solutions are there?

1/2x -1/3y= 5
x= 2/3y + 10

Α. There are no solutions
В. There is one solution.
C. There are infinitely many solutions.
D. It is not possible to determine the number of solutions

Answer 1

A

Explanation:

1/2(2/3y) - 1/3y = 5

1/3y - 1/3y = 5

0 ≠ 5

No Solutions

These are linear equations and, when graphed, are parallel
