Answer 2

Question:

Solve the given equations.

1) $\displaystyle{\sf\:\dfrac{x\:-\:3}{5}\:-\:2\:=\:-\:1}$

2) $\displaystyle{\sf\:3\:(\:x\:-\:1\:)\:+\:7\:=\:11}$

Answer:

1) $\displaystyle{\boxed{\red{\sf\:x\:=\:8\:}}}$

2) $\displaystyle{\boxed{\pink{\sf\:x\:=\:\dfrac{7}{3}}}}$

Step-by-step-explanation:

1)

The given equation is

$\displaystyle{\sf\:\dfrac{x\:-\:3}{5}\:-\:2\:=\:-\:1}$

Now,

$\displaystyle{\sf\:\dfrac{x\:-\:3}{5}\:-\:2\:=\:-\:1}$

$\displaystyle{\implies\sf\:\dfrac{(\:x\:-\:3\:)\:-\:2\:\times\:5}{5}\:=\:-\:1}$

$\displaystyle{\implies\sf\:\dfrac{x\:-\:3\:-\:10}{5}\:=\:-\:1}$

$\displaystyle{\implies\sf\:x\:-\:13\:=\:-\:1\:\times\:5}$

$\displaystyle{\implies\sf\:x\:-\:13\:=\:-\:5}$

$\displaystyle{\implies\sf\:x\:=\:-\:5\:+\:13}$

$\displaystyle{\implies\underline{\boxed{\red{\sf\:x\:=\:8\:}}}}$

∴ The solution of the given equation is 8.

2)

The given equation is

$\displaystyle{\sf\:3\:(\:x\:-\:1\:)\:+\:7\:=\:11}$

Now,

$\displaystyle{\sf\:3\:(\:x\:-\:1\:)\:+\:7\:=\:11}$

$\displaystyle{\implies\sf\:3\:(\:x\:-\:1\:)\:=\:11\:-\:7}$

$\displaystyle{\implies\sf\:3\:(\:x\:-\:1\:)\:=\:4}$

$\displaystyle{\implies\sf\:(\:x\:-\:1\:)\:=\:\dfrac{4}{3}}$

$\displaystyle{\implies\sf\:x\:-\:1\:=\:\dfrac{4}{3}}$

$\displaystyle{\implies\sf\:x\:=\:\dfrac{4}{3}\:+\:1}$

$\displaystyle{\implies\sf\:x\:=\:\dfrac{4\:+\:3}{3}}$

$\displaystyle{\implies\underline{\boxed{\pink{\sf\:x\:=\:\dfrac{7}{3}}}}}$

∴ The solution of the given equation is $\displaystyle{\sf\:\dfrac{7}{3}}$
