Question

-5|3z+8|-5=-20 , can anyone help me with the steps on how to check the solutions ?

Answer 1

steps are
1) add 5
2) divide by -5
3) remove absolute values signs, get two equations
4) solve them

Answer 2

\[-5|3z+8|-5=-25\]
\[-5|3z+8|=-15\]
\[|3z+8|=3\]

Answer 3

those are first two steps. next one is
\[3z+8=3\]
\[3z=-5\]
\[z=-\frac{3}{5}\] or
\[3z+8=-3\]
\[3z=-11\]
\[z=-\frac{11}{3}\]

Answer 4

check my algebra in solving for x. hope they are clear
