Answer:
The equations whose solutions are -1/2 are:
1. 4x + 1 = 6x + 2
2. 3x + 7 = 5x + 8
Step-by-step explanation:
Using the digits 0 to 9 at most one time each, the equations whose solutions are -1/2 are:
1. 4x + 1 = 6x + 2
-2x = 1
x = -1/2
2. 3x + 7 = 5x + 8
-2x = 1
x = -1/2

<h3>☂︎ Answer :- </h3>
<h3>☂︎ Solution :- </h3>
- LCM of 5 , 18 , 25 and 27 = 2 × 3³ × 5²
- 2 and 3 have odd powers . To get a perfect square, we need to make the powers of 2 and 3 even . The powers of 5 is already even .
In other words , the LCM of 5 , 18 , 25 and 27 can be made a perfect square if it is multiplied by 2 × 3 .
The least perfect square greater that the LCM ,
☞︎︎︎ 2 × 3³ × 5² × 2 × 3
☞︎︎︎ 2² × 3⁴ × 5²
☞︎︎︎ 4 × 81 × 85
☞︎︎︎ 100 × 81
☞︎︎︎ 8100
8100 is the least perfect square which is exactly divisible by each of the numbers 5 , 18 , 25 , 27 .
