Check If X Satisfies an Equation

How can you tell if a point is a solution to a system?

• It makes the first equation true.

• The (x,y) coordinates satisfy both equations

• It makes logical sense

• It makes neither equation negative

When you come across a solution that reads 3=4, your answer would be.....

• no solution

• all real numbers

• 3 pizzas = 4 hungry hungry hippos

• one solution

Solve for x: (Remember to check for extraneous solutions!!) l 2x−3 l = 4x−1

• x = 2/3 and x = -1

• Only x=-1/2

• Only x = 2/3

• No Solution

Find the solution.
|x - 1| = 2x + 4

• x = -5

• x = -1

• x = -5 & x = -1

• no solution

Solve for x
l x−1l=5x + 10

• Only x=-3/2

• x = -3/2  and x = -11/4

• x=-11/4

• No Solution

Solve for x
