Question

Find the value of the variables.
Please don't write I don't know and only write with explaination.​​

Answer 1

Answer:

k= -15/2

n=2/3

a=3/2

Step-by-step explanation:

d)

$\frac{k}{ - 3} = \frac{5}{2} \\ k = \frac{5 \times ( - 3)}{2} \\ k = \frac{ - 15}{2}$

e)

$\frac{3}{2} n + 4 = 5 \\ \frac{3}{2} n = 5 - 4 \\ \frac{3}{2} n = 1 \\ n = \frac{2}{3}$

f)

$a + \frac{6}{7} = 3a - 2 \frac{1}{7} \\ a + \frac{6}{7} = 3a - \frac{15}{7} \\ 3a - a = \frac{6}{7} + \frac{15}{7} \\ 2a = \frac{6 + 15}{7} \\ 2a = \frac{21}{7} \\ 2a = 3 \\ a = \frac{3}{2}$

I hope it helps you.
