2a plus 1b equals 2c plus 2d-----2a plus 1b equals 1c plus 2d----- 1a plus 2b equals 3d-----what does 4a equal?
I--2a+b=2c+2d II--2a+b=c+2d III--a+2b=3d * Here if we perform (I)-(II), we get, c=0 * Using the c we can prove b=0 using (I)-(III). * Now replace 'b' & 'c' as 0 in (I), then we get a=d. Email me at yash2008gates@gmail.com for any queries. I will be very thankful to receive your queries.
What is the answer to 2d plus 7 equals 9?
To keep it balanced, whatever you do to one side of the equals, do to the other: 2d + 7 = 9 ⇒ 2d + 7 - 7 = 9 - 7 ⇒ 2d = 2 ⇒ 2d ÷ 2 = 2 ÷ 2 ⇒ d = 1
