Question

please solve this fast please right answer ​

Answer 1

Answer:

1. z = 40

$z = \frac{4(z + 10)}{5} \\ z = \frac{4z + 40}{5} \\ 5z = 4z + 40 \\ 5z - 4z = 40 \\ z = 40$

2. t = - 2

$3(t - 3) = 5(2t + 1) \\ 3t - 9 = 10t + 5 \\ 3t - 10t = 5 + 9 \\ - 7t = 14 \\ t = \frac{14}{ - 7} = - 2$

Answer 2

Answer:

2. given z=4(z+10)/5

5z=4z+40

5z-4z=40

z=40

3. 3t-9=10t+5

-5-9=10t-3t

-14=7t

t=-14/7

t= -2
