Eliminate the y in the following system of equations. What is the result when you add the two equations?
2 answers:
Step-by-step explanation:
To eliminate y we multiply first equation by 4 then add it to the second equation :
4 × (x+y)=2 ➡ 4x + 4y = 8 4x + 4y + 3x -4y = 8 + 27 ➡7x = 35 ➡x = 5 Replace x with the value we found to calculate the value of y : x +y = 2➡5+y = 2 ➡y = -3
