Question

5*(2*x-10)=60

Answer 1

\(5\times\left(2\times x-10\right)=60\)

\(\left(2\times x-10\right)=60\div5\)

\(\left(2\times x-10\right)=12\)

\(2\times x=12+10\)

\(2\times x=22\)

\(\Rightarrow x=22\div2\)

\(\Rightarrow x=11\)

Answer 2

5*(2*x-10)=60

=> 2*x-10=60/5

=> 2*x-10=12

=> 2*x=12+10

=> 2*x=22

=> x=22/2

=> x=11

Answer 3

nhớ k cho mik nha

 5 * 2x - 10 = 60

 2x - 10 = 60 : 5 

 2x - 10 = 12

 2x = 12 + 10

 2x = 22

 x = 22 : 2

 x = 11

Vậy x = 11
