Answer 2

Answer:

7) m = 6

8) k = 15

9) a = -12

10) x = 1

11) n = 4

12) r = 11

Step-by-step explanation:

Solution :

Solving all the questions step by step!

7) 1 = 6+m/12

$\longmapsto{\tt{1 = \dfrac{6 + m}{12}}}$

$\longmapsto{\tt{6 + m = 1 \times 12}}$

$\longmapsto{\tt{6 + m = 12}}$

$\longmapsto{\tt{m = 12 - 6}}$

$\longmapsto{\tt{m = 6}}$

$\bigstar\: \:\underline{\boxed{\tt{\pink{m = 6}}}}$

• Hence, the value of m is 6.

$\begin{gathered}\end{gathered}$

8) 8 = 3 + k/3

$\implies{\tt{8 = 3 + \dfrac{k}{3}}}$

$\implies{\tt{ \dfrac{k}{3} = 8 - 3}}$

$\implies{\tt{ \dfrac{k}{3} = 5}}$

$\implies{\tt{k = 5 \times 3}}$

$\implies{\tt{k = 15}}$

$\bigstar \: \: \underline{\boxed{\tt{\red{k = 15}}}}$

• Hence, the value of k is 15.

$\begin{gathered}\end{gathered}$

9) -4(-8+a) = 80

$\longmapsto{\tt{ - 4( - 8 + a) = 80}}$

$\longmapsto{\tt{( - 8 + a) = \dfrac{80}{ - 4}}}$

$\longmapsto{\tt{( - 8 + a) = - 20}}$

$\longmapsto{\tt{a = - 20 - ( - 8)}}$

$\longmapsto{\tt{a = - 20 + 8}}$

$\longmapsto{\tt{a = -12}}$

$\bigstar \: \: \underline{\boxed{\tt{\purple{a = - 12}}}}$

• Hence, the value of a is -12.

$\begin{gathered}\end{gathered}$

10) 8(x-1) = 0

$\implies\tt{8(x - 1) = 0}$

$\implies\tt{8x - 8 = 0}$

$\implies\tt{8x = 0 + 8}$

$\implies\tt{8x = 8}$

$\implies\tt{x = \dfrac{8}{8}}$

$\implies\tt{x = 1}$

$\bigstar \: \: \underline{\boxed{\tt{\blue{x = 1}}}}$

• Hence, the value of x is 1.

$\begin{gathered}\end{gathered}$

11) n/2 - 1 = 1

$\longmapsto{\tt{\dfrac{n}{2} - 1 = 1}}$

$\longmapsto{\tt{\dfrac{n}{2} = 1 + 1}}$

$\longmapsto{\tt{\dfrac{n}{2} = 2}}$

$\longmapsto{\tt{n = 2 \times 2}}$

$\longmapsto{\tt{n = 4}}$

$\bigstar \: \: \underline{\boxed{\tt{\orange{n = 4}}}}$

• Hence, the value of n is 4.

$\begin{gathered}\end{gathered}$

12) 1 = r-3/8

$\implies{\tt{1 = \dfrac{r - 3}{8}}}$

$\implies{\tt{r - 3 = 1 \times 8}}$

$\implies{\tt{r - 3 = 8}}$

$\implies{\tt{r = 8 + 3}}$

$\implies{\tt{r = 11}}$

$\bigstar \: \: \underline{\boxed{\tt{\green{r = 11}}}}$

• Hence, the value of r is 11.
