Is anyone good at elimination method? I will give 10 points to the person that answer the question. :)

Jill wants to solve the following system using the elimination method:

y = x + 8
y = 3x − 11

What number should the equation y = x + 8 be multiplied by to eliminate x?

Sagot :

To eliminate x, the coefficients of x's in both equations should be opposite numbers. Since the coefficient of x in the second equation is 3, the coefficient in the first equation should be -3. So she should multiply the first equation by -3.

-3! 
-3y=-3x-24
y=3x-11
-2y=-35
y=17.5
