Question 433602: Solve using systems of equations
x+4y=3 (1)
x=4-4y (2)
Answer by algebrahouse.com(1659) About Me  (Show Source):
You can put this solution on YOUR website!
x + 4y = 3
x = 4 - 4y

4 - 4y + 4y = 3 {substituted 4 - 4y, in for x, into top equation}
4 = 3 {combined like terms}
= no solution

Note:
- when solving a system of equations, and the variable disappears, leaving
a false statement, there is "no solution", meaning these two lines never meet.
They are parallel lines.
- When solving a system of equations, and the variable disappears, leaving a
statement that is always true, there are "infinite solutions", meaning the two lines are the same.
