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! :)
Answer:
the answer is 1.421792e+17
I only did times 5412563 cause that's all i could see in the picture
0.5x-9 = 4x+5
add 9 to both sides
0.5x = 4x+14
subtract 4x from each side
-3.5x =14
x = 14/*3.5
x = -4
