Given the equations 2x+4/3 y=1 and y-9/13 x=9, by what factor would you multiply the first equation so that combining the two equations would eliminate x?

-9/26
9/26
1/2
-9/13

9/26

Step-by-step explanation:

To eliminate variable x  we need to make the coefficient of x same and different signs.

In the first fraction the coefficient of x is 2 and i the second fraction the coefficient of x is 9/13

To find the factor that make the coefficient same , we divide 9/13 by 2

9/13 divide by 2 is 9/26

LEts multiply 9/26 and check

9/26 times 2x becomes 9/13 x

We already have same -9/13 x in the second fraction

When we add both x  terms then it becomes 0. x will be eliminated
