Equation:
Solution:​

Answer 1

Answer:

Equation: 2/3*x - 0 - 4 = 0.

Solution: x=6, s=0

Step-by-step explanation:

Let the unknown number be x.

ATQ (according to question),

equation:

2/3*x - s = 4

=) 2/3*x - s - 4 = 0 ( transposing- an positive number becomes negative  

                               when it moves from R.H.S. to L.H.S. or vice versa)

solution:

taking s=0

2/3*x - 0 - 4 = 0

2/3*x - 4 = 0

2/3*x = 4     (transposing- an negative number becomes positive when it

                     moves from L.H.S. to R.H.S. or vice versa)

2x=4*3     (transposing- an number in denominator moves to the numerator

                 when it moves from R.H.S, to L.H.S.)

2x=12

x = 12/2       (transposing- an number in the numerator moves to  

                    denominator when moved from R.H.S. to L.H.S.)

x=6, s=0

hope it helps!
