Sagot :

The given equations are

[tex]-x+4y=7[/tex][tex]6x-3y=42[/tex]

To find the answer we need to cancel out x or y.

so we have to find the LCM of the coefficients of the corresponding variable.

consider the coefficients of x is -1 in the first equation and 6 in the second equation .

Lcm of -1 and 6 is 6.

Multiplying the first equation by 6.

consider the coefficients of y is 4 in the first equation and -3 in the second equation .

Lcm of 4 and 3 is 12

Multiplying the first equation by 3 and the second equation by 4.

Either one of these is the first step to eliminate variables.
