Hi there!
<u>Here are all the steps into solving this equation :</u>
<u>- 8</u> = 5.4
Add 8 on each side of the equation → 5.4 + 8 = 13.4
= 13.4
Multiply each side of the equation by 5 → 13.4 × 5 = 67
9z <u>+ 4</u> = 67
Subtract 4 from each side of the equation → 67 - 4 = 63
<u>9</u>z = 63
Divide each side of the equation by 9 → 63 ÷ 9 = 7
z = 7
There you go! I really hope this helped, if there's anything just let me know! :)
