Answer 1

\(\dfrac{12}{5}\times x-\dfrac{2}{5}\times x=2022\\ \left(\dfrac{12}{5}-\dfrac{2}{5}\right)\times x=2022\\ 2\times x=2022\\ x=2022\div2\\ x=1011\)

Answer 2

12/5 * x - 2/5 * x = 2022

= x * ( 12/5-2/5) = 2022

= x* 2 = 2022

= x = 2022 : 2

= x = 1011

Answer 3

\(12/5 * x - 2/5 * x = 2022\)

(12/5-2/5)*x=2022

2*x=2022

x=2022:2

x=1011
