What is the solution to the equation 21x + 3 = 14 ? : p x ≈ -2.133 x ≈ -1.846 x ≈ 3.867 x ≈ 4.154

The answer is ≈0.524... so, none of the above?

Start by moving the three to the other side of the equation. Do this by subtracting 3 from both sides, so you get 21x=11.

Next, divide both sides by 21. This will give you x=11/21, which is ≈0.524.

However, I do not see this as one of the answers. I get why you might be confused!

x≈-2.133

in exact form it is ln (14) over ln (21) all subtracted by 3. The answer comes to -2.133
