Homework Help: Intermediate Algebra

Posted by Jordan on Thursday, October 7, 2010 at 12:42pm.

Determine whether the point (1, 8) is a solution of the system
2x + 6y = 50
10x + 0y = 10
by substituting the point into each equation.

So far I have:
2x=6y=50
y=50-2x

10x+10y=10
10x+0(50-2x)=10
10x+0=10
x=10

y=50-2x
y=50-2(1)
y=50-2
y=48

PLEASE HELP! I'm lost. I've had tutoring and still do not understand fully.
