Question

9x-2y=30x+2y=30 what is the answer

Answer 1

The solution to the system of equations is x = 6 and y = 12

Explanation:

We can use the elimination method to find the solution to the system of equations. This is done by adding or subtracting the equations to "eliminate" one variable.

`9x-2y=30`

`x+2y=30`

Adding the equations allows us to eliminate the y variable and solve for x.

`9x+-2y+2y=30+30`

`10x=60`

`x=6`

Now that you have the value of x, substitute it back into one of the original equations to solve for y. Let's use the second equation: x+2y=30.

`x+2y=30\\6+2y=30\\2y=24\\y=12`

So, the solution to the system of equations is x = 6 and y = 12.
