Answer 1

Ko biết😋🐖🐶🐷

Answer 2

a,\(6x-5=631\)

\(6x=636\)

\(x=106\)

b,\(x-7=\left(-12\right)+\left(-8\right)\)

\(x-7=-20\)

\(x=-13\)

Answer 3

\(6.x-5=631\)

\(6.x=631+5=636\)

\(x=636:6=106\)

Vậy \(x=106\)

Answer 4

6x - 5 = 631

6x = 631 + 5

6x = 636

x = 636 : 6

x = 106

Vậy x = 106

x - 7 = (-12) + (-8)

x - 7 = -20

x = (-20) + 7

x = -13

Vậy x = -13

Answer 5

a) \(6.x-5=631\)

\(\Leftrightarrow6.x=631+5\)

\(\Leftrightarrow6.x=636\)

\(\Leftrightarrow x=106\)

Vậy : \(x=106\)

b) \(x-7=\left(-12\right)+\left(-8\right)\)

\(\Leftrightarrow x-7=-20\)

\(\Leftrightarrow x=-20+7\)

\(\Leftrightarrow x=-13\)
