Question

3x-2y=8
5x-2y=9

using elimination method.. please help.

Answer 1

If you subtract the bottom from the top, you eliminate y, leaving

-2x = -1

Now you have x, and you can use that value to find y.

Answer 2

Aren't we suppose to get rid of the -2 to get x.. by dividing on both sides?

Answer 3

using elimination method, what is the value of x in the equations 3x - 2y = 8 and 5x + y = 9?

Answer 4

using determinant method, what is the value of x in the equations 3x + 2y = "-10" and 5x + 3y = "-16?"

Answer 5

using determinant method, what is the value of x in the equations 3x + 2y = "-10" and 5x + 3y = "-16?"
