Question

2x + 3y = -9 -x + 4y = 10 Solve the system

Answer 1

Answer:

x = -6

y= 1

Step-by-step explanation:

make one of the variables equal to each other

4(2x+3y) = -9

3(-x+4y) = 10

subtract

8x+12y = -36

- -3x+12y =30

----------------------

11x = -66

x = -6

plug back in to find y

8(-6)+12y = -36

12y= 12

y = 1
