#Maths - METHOD ) BILOPAN Math Notes ( Elimination Method Used to solve simultaneous linear equations two variables and J) Steps to Solve using General Form Bilopan Method bi) = Ct Q1* + equations Write the two 02y = C2 02*+ Make coefficients of equal X O (by multiplying ) C102 - C2 01 . X = Add or Subtract the equations 01 02 _ 020( One variable eliminated gets 01C2 - 02 C1 remaining variable Solve for the 0102 0201 Substitute value in any equation 10 Tind other variable @mwharshit Example 1 Exomple 2 : Solve Solve 2x +y = 7 2x + Y = 7 +) = 5 X = Y =1 both equations Add Solution 2* + Y+ *-Y = 7+1 (2x+ ٧)-(x+ ٧) = 7 - 5 3X २x-x+)-)= 2 X= 2 X = 8 in (2x+y = 7) equation Put X= 2 in 2nd Put X (8) +y = 7 +)= २ +)= 5 1 23 +)= _)= 3 21 1 Answer = 2 , ) = 3` 5 Trick Formula Tor Exams Remember C102 - C2 01 If ax + by = C Make coeTTicients equal q102 02 01 02X + 02/ = C2 3 Add/Subtrqct cqrefully 01C2 = 02C1 d Substitute to Find other value 0102 = 0201 METHOD ) BILOPAN Math Notes ( Elimination Method Used to solve simultaneous linear equations two variables and J) Steps to Solve using General Form Bilopan Method bi) = Ct Q1* + equations Write the two 02y = C2 02*+ Make coefficients of equal X O (by multiplying ) C102 - C2 01 .
