Question

solve by elimination: 3x+7y=23 -3x-7y=-17 (3,3) (-3,3) no solution arn

Explanation:

Step1: Add the two equations

Add the equations \(3x + 7y = 23\) and \(-3x - 7y = -17\) together.
\((3x + 7y)+(-3x - 7y)=23+(-17)\)
Simplify the left - hand side: \(3x - 3x+7y - 7y = 0\)
Simplify the right - hand side: \(23-17 = 6\)
We get \(0 = 6\), which is a false statement.

Answer:

No solution
