Question 287386: please walk me through this problem to use as an exampl?
Solve each system by substitution. Determine whether the equations are independent, dependent, or inconsistent.
y = -3x + 19
y = 2x - 1
Answer by richwmiller(17219) (Show Source): You can put this solution on YOUR website!
since both are equal to y, set them equal to each other and solve for x
-3x + 19 = 2x - 1
add 3x tbs
19=5x-1
add 1 tbs
20=5x
divide bs by 5
4=x
now solve or y
y=2x-1
y=8-1
y=7
(4,7)
