Question

fay wants to solve the system 2x-3y=5 and 3x+2y=-5 using elmination. She multiplies the second equation by 1.5 to get 4.5x+3y=-7.5.

Answer 1

Explanation:

So using elimination:

2x - 3y = 5

+ 4.5x + 3y = -7.5 From here add to eliminate the y variable

6.5 x = -2.5

divide both sides by 6.5

6.5x/6.5 = -2.5/6.5

x = - 5/13 or -0.3846
