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

Fofino [41]

★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: $10

Step-by-step explanation:

Given

Robin and his four friends bought tickets for $\$12$ each

If each one of them bought a calculator then the total spendings are $\$110$

Suppose the cost of each calculator is $\$\ x$

Cost per person is given by $x+\$12$

For the group, it is $5(x+12)$

Equate this to total spendings

$\Rightarrow 5(x+12)=110\\\Rightarrow x+12=22\\\Rightarrow x=\$\ 10$

thus, the cost of each calculator is $\$ 10$
