We can access the solution out of the solution dictionary using regular dictionary indexing. The first cord, cord CE, is 30 degrees above the horizontal and to the right.

Consider the following engineering statics problem which can be solved with symbolic math and Sym Py. The second cord, cord BD, is 45 degrees to the left and above the horizontal. Sym Py equation objects are instantiated with expressions equal to zero.

Even simple math problems become easier to solve when broken down into steps.

From basic additions to calculus, the process of problem solving usually takes a lot of practice before answers could come easily.

You can solve all problems from the basic math section plus solving simple equations, inequalities and coordinate plane problems.

You can also evaluate expressions, factor polynomials, combine/multiply/divide expressions.

But, as with all math skills, you have to start out with the basic foundation and then build on it. Now simplify the equation by doing the math: 2-2 x=7-2=0 x=5, or x = 5. The equations may work out to where the answer for x may actually contain another letter itself. You want to solve for x, just like before, so get x by itself on one side of the equation.

In algebra, solving algebraic equations starts with practicing equations in which you solve for x, which simply means you have to figure out the unknown amount. The most basic algebra equation involves simple addition or subtraction with one unknown quantity, such as 2 x = 7. Check your work by substituting the answer, 5, into the equation for x.

If the expression was not equal to zero, simply subtract both sides by the term on the right-hand side of the equals sign and use the resulting expression (equal to zero) to create the Sym Py equation object. The dictionary keys are the variable names and the dictionary values are the numerical solutions.

The numerical solutions can be pulled out of the dictionary using regular Python dictionary access.
