Question

question 1 20 pts 1) aria wrote the following system of linear equations on the board: 2x + 3y=-5 7x - 3y = 23 which equation is the result of adding these two equations? -5x=-18 5x = 28 9x = 28 9x = 18

Explanation:

Step1: Add the left - hand sides

Add the left - hand sides of the equations \(2x + 3y\) and \(7x-3y\). \((2x + 3y)+(7x - 3y)=2x+7x+3y - 3y=9x\).

Step2: Add the right - hand sides

Add the right - hand sides of the equations \(-5\) and \(23\). \(-5 + 23=18\).

Answer:

\(9x = 18\)
