Solve the equation.

Dafna1 [17]

Hi there!

Here are all the steps into solving this equation :

$\frac{9z+4}{5}$ - 8 = 5.4

Add 8 on each side of the equation → 5.4 + 8 = 13.4

$\frac{9z+4}{5}$ = 13.4

Multiply each side of the equation by 5 → 13.4 × 5 = 67

9z + 4 = 67

Subtract 4 from each side of the equation → 67 - 4 = 63

9z = 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! :)
