**TI 84 Plus CE: Linear Equation Algebra Drill**

Note: This program is recommended for the TI-84 Plus CE with OS 5.2 or later.

The program ALGDRILL has the user answer ten questions to solve for x in the following linear equation:

A * X + B = C

The values of A, B, and C are randomly selected from -10 to 10. Note that A ≠ 0.

For(K,1,10)

0→A:0→B

Repeat A≠0 and B≠0

randInt(10,10)→A

randInt(10,10)→B

End

randInt(10,10)→C

(C-B)/A→X

Input Y

If Y=X

Then

Disp “CORRECT :)”,X ▶Frac

S+1→S

Else

Disp “INCORRECT.”,”ANSWER: “,X▶Frac

End

Pause

End

ClrHome

Disp “SCORE: “+toString(S)+”/10”

If S≥8

Disp “WELL DONE!”
