Question

tìm x 121:11-(4.x+5)=4

Answer 1

121:11-(4.x+5)=4

11-(4.x+5) = 4

      4.x+5  = 7

      4.x      = 2

        x       = 2/4

Answer 2

\(11-4x-5=4\)

\(6-4x=4\)

\(4x=6-4\)

\(4x=2\)

\(x=\frac{1}{2}\)

Answer 3

121 : 11 - (4.x + 5) = 4

11 - (4.x + 5) = 4

4x + 5 = 11 - 4

4x + 5 = 7

4x = 7 - 5

4x = 2

x = 1/2
