Hi I need help with this one problem. It's on page 167 algebra with pizzazz. It has to use the addition method.
3x5y=7
5x2y=1

J,
How do you start it then I can solve it easily. I'm not cheating.!!!!!

Reiny,
You want either the x's or the y's to have opposite coefficients.
let's work on the y's
#1 times 2 > 6x  10y = 14
#2 times 5 > 25x + 10y =5
add them:
19x = 19
x = 19/19 = 1
back in #1:
3(1)  5y = 7
=5y = 7 + 3 = 10
y = 2
x = 1 , y = 2
