C+ax=dx this one has all variables and no numbers

sergeinik [125]

That's OK, but you have not said which variable you want to solve it for.

To solve for 'x':
 c + ax = dx

Subtract c from each side: ax = dx - c

Subtract dx from each side: ax - dx = -c

Factor the left side: x (a - d) = -c

Divide each side by (a - d) : x = -c / (a - d) or x = c / (d - a) .

To solve for 'c': 
 c + ax = dx

Subtract ax from each side and factor: c = x (d - a) 

To solve for 'd': 
 c + ax = dx

Divide each side by 'x': d = c/x + a .

To solve for 'a':
 c + ax = dx

Subtract 'c' from each side: ax = dx - c

Divide each side by 'x': a = d - c/x .

2⋅(3 6 ⋅ 3−5) Evaluate the expression.

aleksley [76]

On 3 and 6 you did not clarify whether it is addition, subtraction, multiplication, or division.
Therefore, I have worked out all possible solutions.

If 2(3 - 6 x 3 - 5) then the solution is 12.

If 2(3 + 6 x 3 - 5) then the solution is -36.

If 2(3 / 6 x 3 - 5) then the solution is -2.

If 2(3 x 6 x 3 - 5) then the solution is -72.
