Question

1) 2m×n = 5k; 4) m - n = 3j; 2) m+ j= n× k; 5) 0,12m 20(k - n); 3) m:n = k:1j6) 3m =5k. ​

Answer 1

1. $2m*n=5k\\\\m=\frac{5k}{2n}$

________________

2. $m+j=n*k\\\\m=-j+kn$

________________

3. $m:n=k:1j\\\\\frac{m}{n}=kj\\\\m=jkn$

________________

4. $m-n=3j\\\\m=3j+n$

________________

5. $0,12m*20(k-n)\\\\2,4*(k-n)\\\\2,4km-2,4mn$

________________

6. $3m=5k\\\\m=\frac{5}{3}k$
