Question

95 – 5(x + 2) = 45

Answer 1

Answer 2

\(95-5\left(x+2\right)=45\\ \Rightarrow5\left(x+2\right)=50\\ \Rightarrow x+2=10\\ \Rightarrow x=8\)

Answer 3

95-5(x+2)=45

5(x+2)=95-45

5(x+2)=50

x+2=10

x=8

Answer 4

=8

Answer 5

    95 – 5 ( x + 2 ) = 45

⇔        5 ( x + 2 ) = 95 - 45

⇔        5 ( x + 2 ) = 50

⇔               x + 2  = 10

⇔                      x = 8

Answer 6

\(95-5\left(x+2\right)=45\)

\(-5\left(x+2\right)=45-95\)

\(-5\left(x+2\right)=-50\)

\(x+2=-50+2\)

\(x+2=-48\)

\(x=-48-2\)

\(\Rightarrow x=-50\)

 

Answer 7

Ta có: \(95-5\left(x+2\right)=45\)

\(\Leftrightarrow5\left(x+2\right)=50\)

\(\Leftrightarrow x+2=10\)

hay x=8
