Solve each system by substitution. Determine whether the
equations are independent, dependent, or inconsistent. Can you please help me to solve this equation
y=-3x+19
y=2x-1
-------------------
The slopes are different so the lines meet at a
point, so the system is consistent.
-----------------------------------
Substitute y = 2x-1 into the 1st equation and solve for "x:
2x-1 = -3x+19
5x = 20
x = 4
---------------
Since y = 2x-1, y = 2*4-1, y = 7
=====================================
