Elimination method 3x+4y=18 9x-5y=3
1 answer:
Answer:
The solution would be (10, -3)
Step-by-step explanation:
In order to solve using elimination, multiply the top equation by -3 and then add the equations together.
-9x - 12y = -54
9x - 5y = 3
---------------
17y = -51
y = -3
Now that we have a value for y, we can put it into either equation and solve for x.
3x + 4y = 18
3x + 4(-3) = 18
3x - 12 = 18
3x = 30
x = 10
