Question

Solve: |2t + 5| = 3
A. {1, 4}
B. {-1, -4}
C. {-1, 4}
D. {1, -4}

Answer 1

when |a| = b
then a=b or a =-b
so what about |2t+5| = 3 ??

Answer 2

i'm confused

Answer 3

like we get 2 equations, one with positive sign and one with negative sign on right side.
so for |2t+5|=3
we would have
2t+5 = 3 OR 2t+5 = -3

can you solve these 2 simple linear equations ?

Answer 4

t=−1

t=−4

Answer 5

correct!
thats your answer :)
