Question

enter the solution of the system of equations below as an ordered pair.
y+x=10
10y+20x=110

ajprincess · Answer

Multiply the first eqn by 10
then subtract t frm the sec eqn.
Then u wil get an eqn in terms of x.
solve for x.
Substitute the value of x in the first eqn to find y.

Alternatively, you can do it this way:
$$y+x=10$$$$10y+20x=110$$Put one of the variables in terms of the other.  I'll use the first equation to do that:$$y=10-x$$Now substitute that equation into the second for every place you see a y:$$10(10-x)+20x=110$$Now solve for x.  Once you have a value for x plug it back into the first equation to get y.
