In step 1 of Elimination, what do we do?

• Who decide what variable to ingore

• We decide what variable to eliminate

• We substitute a number into the other

In step 1 of Elimination, what do we do?

• We make both equations have the same amount of the variable on each side

• We substitute variables that we already found on one side

In step 1 of Elimination, what do we do?

• Substitute the solution into DIFFERENT equation and solve for the some other variable

• Substitute the solution into THE SAME equation and solve for the some other variable
