GRAPHING CONS
1) hard to graph by hand. Often you need a graphics calculator or a computer software like maple or matlab. Or the graph has to be given.
2) hard to tell the exact solution, just by observing point of intersection. for example if x = 2.8675, the viewer would say x= 3.
3) sometimes not easy to decide the axis window of y and x axis. For example if the solution is very large like x = 100000 and your graph ends at x = 100, you cannot see the solution
SUBSTITUTION CONS
1) Becomes tedious if a system has too many equations or variables
ELIMINATION PROS/CONS
1) basically same as substitution
Check the angle. If it they are less than 90°<span> , so they will result in acute angles. </span>
Step-by-step explanation:
t = 4
u = 6 + 2
Find t - u
solu
t - u
= 4 - ( 6 + 2 ) = 4 - 8
Answer is -4
