Solver is the third function and allows you to determine the value of any variable in a formula or
equation. You can input any formula exactly as it appears using a for any variables. In this example,
we will solve a linear equation and a formula.
5. To nd the value of x in the following equation, 2(x - 5) = -3x + 2, input the following, starting from
the initial Equation Editor Screen:
• e2(f-5)L.n3f+2lu
Note: Selecting q will take you back to the previous screen where you can edit and re-solve
the previous equation or begin a new problem.
Note: In the last screen, “Lft” and “Rgt” represent the values of the left and right sides
of the equation using the value of the solution; this is the calculator’s way of checking the
solution.
You can also enter a formula, assign values, and solve for a specic variable using the Solver
function of the Equation Editor.
