In order to solve this problem, we must isolate the x on one side of the equation. The first step is to remember that the inverse operations of addition and multiplication are subtraction and division. The next step is to 'move' the 3 to the right side of the equation by subtracting it from both sides of the equation.

Daniel L. If both x and y are variables, then the answer is: "No, it is not a linear equation.". The linear equation is a sum of terms like " Ax " where x is a variable, and A is a number or a constant.

The additive inverse of a polynomial is the same polynomial with the signs of the terms changed. Thus we change the signs of each term in the subtrahend. write the new signs in circles above the original signs, and add like terms using the new signs.

No, sinh is a hyperbolic function of sine. Sin^-1 is inverse of sine. You use the inverse to find angles. To enter sinh to press hyp then sin.
