• -50, 20

• -45, 30

• 5, 25

• 0, 35

What is the first step when solving an absolute value equation?

• Eliminate the y

• Switch x and y

• Eliminate any outside terms

• Set everything = to 0

what is an absolute value equation?

• equations where the variable is without an absolute value operator

• when the equations are always positive

• when the equations are always negative

solve for t.
