Answer:
187
Step-by-step explanation:
Least common multiple:
To find the required number,
- Find the LCM of 30 , 36 and 45
- Then add 7 to the LCM
30 = 2 * 3 * 5
36 = 2 * 2 * 3 * 3 = 2² * 3²
45 = 2 * 3 * 3 = 2 *3²
LCM = 2² * 3² * 5
= 4 * 9 * 5
= 180
Required number = 180 + 7
= 187
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u>
And we need to solve the equation using Substituting method . So on taking the first equation ,
<u>Put </u><u>this</u><u> </u><u>value</u><u> </u><u>in </u><u>(</u><u>ii)</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Put </u><u>this</u><u> </u><u>Value</u><u> </u><u>in </u><u>(</u><u>I)</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Hence</u><u> the</u><u> </u><u>Value</u><u> </u><u>of </u><u>x </u><u>is </u><u>2</u><u>1</u><u> </u><u>and </u><u>y </u><u>is </u><u>(</u><u>-</u><u>6</u><u>)</u><u> </u><u>.</u>
6 times 6 is 36
6 x 6 = 36
