Explanation Given information: The system of equations is { x − 2 y = 1 x 3 − 2 x 2 = y . Calculation: The first equation is, x − 2 y = 1 Simplify the above equation to obtain y in terms of x as, x − 2 y = 1 − 2 y = 1 − x 2 y = x − 1 y = x − 1 2 Consider y as y 1 in the above equation. y 1 = x − 1 2 The second equation is, x 3 − 2 x 2 = y y = x 3 − 2 x 2 Consider y as y 2 in the above equation. y 2 = x 3 − 2 x 2 To obtain the solution of the equations { x − 2 y = 1 x 3 − 2 x 2 = y , first turn ON the calculator then press the WINDOW button and insert the equations y 1 = x − 1 2 and y 2 = x 3 − 2 x 2 as shown in Figure 1. Now, press the WINDOW button and set the viewing window as shown in Figure 2. After this, press the GRAPH button and the graph is obtained as shown in Figure 3. To obtain the intersection of y 1 = x − 1 2 and y 2 = x 3 − 2 x 2 up to two decimal press MODE and select 2 in Float as, Now, press 2nd then TRACE and select the option 5.Intersect to obtain the intersection of y 1 = x − 1 2 and y 2 = x 3 − 2 x 2 .
