\sf{3. \ \ Given : \dfrac{2}{3} - \dfrac{5}{4} + \dfrac{7}{2}}

Let us solve the first two fractions : The LCM of 3 and 4 is 12

\sf{\implies \dfrac{4(2) - 5(3)}{12} + \dfrac{7}{2}}

\sf{\implies \dfrac{8 - 15}{12} + \dfrac{7}{2}}

\sf{\implies \dfrac{-7}{12} + \dfrac{7}{2}}

LCM of 2 and 12 is 12

\sf{\implies \dfrac{-7 + 7(6) }{12}}

\sf{\implies \dfrac{-7 + 42}{12}}

\sf{\implies \dfrac{35}{12}}

\sf{\implies 2 +\dfrac{11}{12}}

\sf{\implies 2 \dfrac{11}{12}}

---------------------------------------------------------------------------------------

\sf{4. \ \ Given : \dfrac{(2 - 7)^2 + 5}{3}}

\sf{\implies \dfrac{(-5)^2 + 5}{3}}

\sf{\implies \dfrac{25 + 5}{3}}

\sf{\implies \dfrac{30}{3}}

\sf{\implies 10}

  3. lcm of 3 and 2 is 6 hence 2/3+7/2= 25/6
  4. 25/6-5/4....lcm of 6 and 4 is 12 hence 25/6-5/4=35/12

A) 2x-5y=10
r-ruslan [8.4K]

Answer:

Step-by-step explanation:So to find it you need to eliminate either x or y. 2x-5y=10 over 4x-10y=20. In order to get y to eliminate you need one equation to have a positive 10y and a negetive 10y. So you multiply both sides of the first equation by negetive 2 so it is now, -4x+10y=-20. Notice how all the numbers in both equations are opposite this gives us ims infinitaly many sollutions. So it is not A. Or b it will do the same thing. The answer is either D or C hope this helps
