Question

Factorise:- If 3x+2y =8 what is the value of 21x +14y ?

Answer 1

Answer:

3x+2y=8. take the 8 to the left side.so we get 3x+2y-8=0.factorization method splitting the middle term mutiply 3 and -8 we get -24. if we mutiply 6and -4 we get -24 and when we add we get 2the value for x is -2 and 4/3. substitute both the values separately in the equation.
