Question

Solve this equation. Enter your answer in the box. 13(y+7)=3(y−1).

Answer 1

★To Solve :

$\rm\blue{13(y+7) = 3(y-1)}$

⠀⠀⠀⠀⠀

★SOLUTION :

$\rm\red\leadsto{13(y+7) = 3(y-1)}$

$\rm\red\leadsto{13\times{y}+13\times7= 3\times{y}-3\times1}$

$\rm\red\leadsto{13y+91=3y-3}$

$\rm\red\leadsto{13y-3y=-3-91}$

$\rm\red\leadsto{10y=-94}$

$\rm\red\leadsto{} y =\dfrac{ { \cancel{-94}}^{ \:-45 } }{ { \cancel{10}}^{ \: 5} }$

$\rm\red\leadsto{y=}\dfrac{-47}{5}$

Answer 2

★Answer

$\red{13(y + 7) = 3(y - 1)} \\ \\ \color{red}\dashrightarrow \: 13y + 91 = 3y - 3 \\ \\ \color{pink} \dashrightarrow \: 13y - 3y = - 3 - 91 \\ \\ \pink{ \dashrightarrow \: 10y = - 94} \\ \\ \purple{ \dashrightarrow \: y = \frac{ \cancel{- 94} {}^{ - 47} }{ \cancel{10} {}^{5} } }\\ \\ \green{ \dashrightarrow \: y = \frac{ - 47}{5} }$

Hence, The Answer is

$=\frac{ - 47}{5}$
