| 9) Solve 5 - a = 8 a = -3 Answer:_______________ |
| 10) Solve 11 - y = 7 y = 4 Answer:_______________ |
| 1) Solve 13 - x = 8 x = 5 SOLUTION 1 : 13 - x = 8 ⇒ - x = 8 - 13 ( on transposing +13 becomes - 13 ) ⇒ - x = -5 ⇒ (-1) (-x ) = (-1) -5 ( multiplying by (-1), both sides ) x = 5
|
| 2) Solve 10 - y = -6 y = 16 SOLUTION 1 : 10 - y = -6 ⇒ - y = -6 - 10 ( on transposing +10 becomes - 10 ) ⇒ - y = -16 ⇒ (-1) (-y ) = (-1) -16 ( multiplying by (-1), both sides ) y = 16
|
| 3) Solve 3 - x = 7 x = -4 SOLUTION 1 : 3 - x = 7 ⇒ - x = 7 - 3 ( on transposing +3 becomes - 3 ) ⇒ - x = 4 ⇒ (-1) (-x ) = (-1) 4 ( multiplying by (-1), both sides ) x = -4
|
| 4) Solve 11 - a = 7 a = 4 SOLUTION 1 : 11 - a = 7 ⇒ - a = 7 - 11 ( on transposing +11 becomes - 11 ) ⇒ - a = -4 ⇒ (-1) (-a ) = (-1) -4 ( multiplying by (-1), both sides ) a = 4
|
| 5) Solve 13 - a = -6 a = 19 SOLUTION 1 : 13 - a = -6 ⇒ - a = -6 - 13 ( on transposing +13 becomes - 13 ) ⇒ - a = -19 ⇒ (-1) (-a ) = (-1) -19 ( multiplying by (-1), both sides ) a = 19
|
| 6) Solve 2 - y = 10 y = -8 SOLUTION 1 : 2 - y = 10 ⇒ - y = 10 - 2 ( on transposing +2 becomes - 2 ) ⇒ - y = 8 ⇒ (-1) (-y ) = (-1) 8 ( multiplying by (-1), both sides ) y = -8
|
| 7) Solve 15 - x = 5 x = 10 SOLUTION 1 : 15 - x = 5 ⇒ - x = 5 - 15 ( on transposing +15 becomes - 15 ) ⇒ - x = -10 ⇒ (-1) (-x ) = (-1) -10 ( multiplying by (-1), both sides ) x = 10
|
| 8) Solve 15 - a = -5 a = 20 SOLUTION 1 : 15 - a = -5 ⇒ - a = -5 - 15 ( on transposing +15 becomes - 15 ) ⇒ - a = -20 ⇒ (-1) (-a ) = (-1) -20 ( multiplying by (-1), both sides ) a = 20
|
| 9) Solve 5 - y = 8 y = -3 SOLUTION 1 : 5 - y = 8 ⇒ - y = 8 - 5 ( on transposing +5 becomes - 5 ) ⇒ - y = 3 ⇒ (-1) (-y ) = (-1) 3 ( multiplying by (-1), both sides ) y = -3
|
| 10) Solve 11 - x = 7 x = 4 SOLUTION 1 : 11 - x = 7 ⇒ - x = 7 - 11 ( on transposing +11 becomes - 11 ) ⇒ - x = -4 ⇒ (-1) (-x ) = (-1) -4 ( multiplying by (-1), both sides ) x = 4
