Question 226054: Please help me with this problem.
Use substitution to solve each system of equation? State whether it has no solution or many solutions.
x+5y=-3
3x-2y=8
Answer by LtAurora(115) (Show Source): You can put this solution on YOUR website!
The first equation is easiest to get a variable by itself, so move the 5y to the other side bu subtracting it from both:
Then we can plug this into the second equation for x:
Distribute the 3:
Combine like terms:
Move the -9 to the other side by adding it:
Divide both sides by -17:
We can plug this back in to get x:
So, the answer is (2,-1). It has only one solution as the lines cross at that point.
