Today we learned how to SOLVE and CHECK simple algebraic equations.
For example:
SOLVE:
x - 12 = 9 (Think: What can I do to both sides to get x by itself?)
x - 12 +12 = 9 +12 (Add twelve to both sides)
x = 19 (Since -12+12 is zero, they cancel each other out)
CHECK: x - 12 = 19 (Copy out the original equation)
19 - 12 = 19 (Substitute the answer you got above)
19 = 19 ☺ (Be sure to give yourself a smiley face or check mark if correct!)
