Question

Solve this equation.
13(y+7)=3(y−1).

Answer 1

Answer:

Explanation:

★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:

y=9.4

Step-by-step explanation:

13(y+7)=3(y-1)

13y+91=3y-3

13y-3y=-3-91

10y=-94

y=-94/10

y=-9.4
