Question 212878
Solve by graphing:
{{{5u+v = 21}}}
{{{5u = v+29}}} 
Rewrite the equation in slope-intercept form:
{{{v = -5u+21}}}
{{{v = 5u-29}}}
Graph:
{{{graph(400,400,-2,10,-5,5,-5x+21,5x-29)}}}
From the graph, the solution is: (5, -4) or u = 5 and v = -4
The system is a consistent system since there is at least one solution.
