Question

solve 2(y-5/2)= 0.3 and "check" ​

Answer 1

Answer:

y=2.65

Step-by-step explanation:

2(y-5÷2)=3÷10

2y-5=3÷10

2y=0.3+5

2y=5.3

y=53÷20

y=26.5÷10

y=2.65

=RHS

2(2.65-5÷2)

2(2.65-2.5)

2(0.15)

0.30

0.3=LHS

Answer 2

$\huge{\tt\red{ANSWER}}\\\\\tt 2\:\times\:(y\:-\:\dfrac{5}{2})\:=\:0.3\\\\\implies\tt 2y\:-\:\dfrac{2\:\times\:5}{2}\:=\:0.3\\\\\implies\tt 2y\:-\:\dfrac{10}{2}\:=\:0.3\\\\\implies\tt 2y\:-\:5\:=\:0.3\\\\\implies\tt 2y\:=\:0.3\:+\:5\\\\\implies\tt 2y\:=\:5.3\\\\\implies\tt y\:=\:\dfrac{5.3}{2}\\\\{\underline{\tt{y\:=\:2.65}}}\\\\\tt Now,\:substitute\:[y\:=\:2.65]\:in\:[2\:\times\:(y\:-\:\dfrac{5}{2})\:=\:0.3]\\\\\therefore\tt 2\:\times\:(2.65\:-\:\dfrac{5}{2})\:=\:0.3\\\\\therefore\tt{0.3\:=\:0.3}$
