Solve this system of equations using the elimination method.
3x – 4y = 2
x + 4y = 10
Hint
Add the two equations together as is.
Answer
Solve the system of linear equations using the elimination method.
2y + 4x = 8
3y + 6x = 1.5
Multiply the first equation by 3, the second by -2, then add them together.
There are no solutions; the lines are parallel.
-x – y = 5
-x + 4y = 15
Subtract the second equation from the first.
(-7, 2)
3y + 6x = 12
There are an infinite number of solutions. The lines are the same.
5y = -10x – 3
Rearrange the variables, then multiply the first equation by -5.
5x – y = 20
7x + y = 10
Add the two equations
