Question

Which of the following. Best describes the solution to the system of equations below?

Answer 1

x=5/2 − 5y/4 => the first sentence

Explanation:

Solve for x in the first equation.

x=5/2−5y/4

12x+15y=30

Replace all occurrences of x

with 5/2−5y/4 in each equation.

30=30

x=5/2−5y/4

Remove any equations from the system that are always true.

x=5/2−5y/4

if y=0 => x=5/2
