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

Fofino [41]

★To Solve :

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

⠀⠀⠀⠀⠀

★SOLUTION :

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

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

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

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

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

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

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

Simplify. (−5 p 4 z 6 u) 3

ser-zykov [4K]

In this expression, solve the multiplication in the parenthesis.
-5×p×4×z×6×u
since multiplication is commutative,
-5×p×4×z×6×u=-5×4×6×p×z×u= -120pzu

Now multiply this by 3.
(-5p4z6u)3 = (-120pzu)3 = -360pzu
