# Thread: Solving 2 equations

1. ## Solving 2 equations

I need help with the following problem. I will appreciate any help to solve this:

x+y=3421
23% of x + 13.5% of y = 684.34

What are the values of x and y so the both of above equations give correct answers.

2. ## Re: Solving 2 equations

$y=3421-x$

$230x+135(3421-x)=684340$

solve the second equation for $x$, then use the first equation to find the value of $y$

3. ## Re: Solving 2 equations

"23% of x + 13.5% of y = 684.34" can be written, as a "real" equation 0.23x+ 0.135y= 684.34. skeeter has gotten rid of the decimal fractions by multiplying the entire equation by 1000.
