Given the following system of equations: 3x + 5y = 30 x + 3y = 10 Which action creates an equivalent system that will eliminate one variable when they are combined?

3 (10-3y) + 4y=30

y=0

x=10

Step-by-step explanation:

You can replace 1 of the 2 variables in order to get a lineal equation.

First equation = 3x+4y=30

second equiation x+3y=10

Second = X=10-3Y--> Now you replace X In the first equation

3 (10-3y) + 4y=30

30-9y+4y=30

-5y=0

y=0

Now replace y with 0---> 3X+0=30--> X=10

So

y=0

x=10
