For the following equations, which coefficients would be easier to make opposites?
2x + 3y = 12
4x - 7y = - 54
2x and 4x
3y and -7y
Let's multiply the top equation by -2. What would be our new equation?
2x + 3y = 12
4x - 7y = - 54
4x - 6y = -24
-4x - 6y = 12
-4x - 6y = 24
-4x - 6y = -24
Now, our equations will look like this
-4x - 6y = -24
4x - 7y = - 54
Let's combine (add) these 2 equations to ELIMINATE the x variable. What would our combined equations be?
-1y = 30
13y = -30
-1y = -78
-13y = -78
Let's solve for y.
-13y = -78
y = 6
y = 1
y = 8
y = 30
