Full solution

Q. Solve using elimination.\newline9x8y=119x - 8y = 11\newline9x9y=189x - 9y = 18\newline(_____, _____)
  1. Write Equations: Write down the system of equations to be solved using elimination.\newline9x8y=119x − 8y = 11\newline9x9y=189x − 9y = 18
  2. Subtract Equations: Subtract the second equation from the first equation to eliminate the variable xx.(9x8y)(9x9y)=1118(9x − 8y) − (9x − 9y) = 11 − 18 This simplifies to:9x8y9x+9y=79x − 8y − 9x + 9y = −7
  3. Combine Terms: Combine like terms to isolate the variable yy.8y+9y=7−8y + 9y = −7y=7y = −7
