Question

100-7(x-5)=65

Answer 1

7.(x-5)=35

=> x-5=5

=> x=10.

Answer 2

Answer 3

\(100-7(x-5)=65\)

\(7(x-5)=100-65\)

\(7(x-5)= 35\)

\(x-5= 35:7\)

\(x-5=5\)

\(x=5+5=10\)

Answer 4

\(100-7\left(x-5\right)=65\)

\(\Leftrightarrow7\left(x-5\right)=35\)

\(\Leftrightarrow x-5=5\)

\(\Leftrightarrow x=10\)

Vậy x = 10

Answer 5

7.(x-5)=35

=> x-5=5

=> x=10.
