Use equation 1 and equation 2 to eliminate the variable 3x - y - 6z = 16 equation 1
-x - 2y + z = -5 equation 2
2x + 3y + 2z = 10 equation 3

Match each equation with the operation you can use to solve for the variable. subtract 10. divide by 10. divide by 5. subtract 18. multiply by 10. add 18. add 10. multiply by 5. 5 = 10p arrowright p + 10 = 18 arrowright p + 18 = 5 arrowright 5p = 10 arrowright
