Question

Find the X COORDINATE OF THE intersection of 9x - 6y = 12 and 3x + 2y =8

Answer 1

Answer:
`x=2`

Explanation:

Given a System of linear equations, the solution of the system is the point
`(x,y)` in which the lines intersect, where "x" is the x-coordinate and "y" is the y-coordinate.

Having the following System of equations:

`\left \{ {{9x - 6y = 12} \atop {3x + 2y =8}} \right.`

You can use the Elimination method to find the value of "x":

-Multiply the second equation by 3.

- Add the equations.

- Solve for "x".

Then, you get:

`\left \{ {{9x - 6y = 12} \atop {9x +6y =24}} \right.\\.......................\\18x=36\\\\x=(36)/(18)\\\\x=2`
