| 9) Solve 11 - y = 5 y = 6 Answer:_______________ |
| 10) Solve 3 - x = 9 x = -6 Answer:_______________ |
| 1) Solve 5 - a = 12 a = -7 SOLUTION 1 : 5 - a = 12 ⇒ - a = 12 - 5 ( on transposing +5 becomes - 5 ) ⇒ - a = 7 ⇒ (-1) (-a ) = (-1) 7 ( multiplying by (-1), both sides ) a = -7
|
| 2) Solve 13 - x = -8 x = 21 SOLUTION 1 : 13 - x = -8 ⇒ - x = -8 - 13 ( on transposing +13 becomes - 13 ) ⇒ - x = -21 ⇒ (-1) (-x ) = (-1) -21 ( multiplying by (-1), both sides ) x = 21
|
| 3) Solve 14 - y = 5 y = 9 SOLUTION 1 : 14 - y = 5 ⇒ - y = 5 - 14 ( on transposing +14 becomes - 14 ) ⇒ - y = -9 ⇒ (-1) (-y ) = (-1) -9 ( multiplying by (-1), both sides ) y = 9
|
| 4) Solve 5 - x = 9 x = -4 SOLUTION 1 : 5 - x = 9 ⇒ - x = 9 - 5 ( on transposing +5 becomes - 5 ) ⇒ - x = 4 ⇒ (-1) (-x ) = (-1) 4 ( multiplying by (-1), both sides ) x = -4
|
| 5) Solve 12 - a = -7 a = 19 SOLUTION 1 : 12 - a = -7 ⇒ - a = -7 - 12 ( on transposing +12 becomes - 12 ) ⇒ - a = -19 ⇒ (-1) (-a ) = (-1) -19 ( multiplying by (-1), both sides ) a = 19
|
| 6) Solve 15 - y = 5 y = 10 SOLUTION 1 : 15 - y = 5 ⇒ - y = 5 - 15 ( on transposing +15 becomes - 15 ) ⇒ - y = -10 ⇒ (-1) (-y ) = (-1) -10 ( multiplying by (-1), both sides ) y = 10
|
| 7) Solve 4 - x = 12 x = -8 SOLUTION 1 : 4 - x = 12 ⇒ - x = 12 - 4 ( on transposing +4 becomes - 4 ) ⇒ - x = 8 ⇒ (-1) (-x ) = (-1) 8 ( multiplying by (-1), both sides ) x = -8
|
| 8) Solve 14 - a = -8 a = 22 SOLUTION 1 : 14 - a = -8 ⇒ - a = -8 - 14 ( on transposing +14 becomes - 14 ) ⇒ - a = -22 ⇒ (-1) (-a ) = (-1) -22 ( multiplying by (-1), both sides ) a = 22
|
| 9) Solve 11 - y = 5 y = 6 SOLUTION 1 : 11 - y = 5 ⇒ - y = 5 - 11 ( on transposing +11 becomes - 11 ) ⇒ - y = -6 ⇒ (-1) (-y ) = (-1) -6 ( multiplying by (-1), both sides ) y = 6
|
| 10) Solve 3 - x = 9 x = -6 SOLUTION 1 : 3 - x = 9 ⇒ - x = 9 - 3 ( on transposing +3 becomes - 3 ) ⇒ - x = 6 ⇒ (-1) (-x ) = (-1) 6 ( multiplying by (-1), both sides ) x = -6
