Solve the equation.

Dafna1 [17]

Hi there!

<u>Here are all the steps into solving this equation :</u>

$\frac{9z+4}{5}$ <u>- 8</u> = 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 <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! :)

One number is 3 more than another number. if you add 12 to 4 times the first number, the result is 5 times the second number. Fi

Answer:

first is -3, second number is 0

Step-by-step explanation:

you have two equations x+3=y and 4*x+12=5*y

Use the first one and write y in terms of x in the second equation:

4*x+12=5*(x+3)

4*x+12=5*x+15

12=5*x-4*x+15

12=x+15

x=-3
