Question

3x-1+2(x+1=5y+1+6y-1

Answer 1

$\huge\blue\star\underbrace\mathtt{\underline{\underline\red{Answer}}}$

On putting x1=X and y1=Y in given equations, we get

3X+5Y=151⇒5X+3Y=1            ...(i)

2X+3Y=121⇒6X+4Y=1            ...(ii)

On multiplying (i) by 6 and (ii) by 5, we get

30X+18Y=6

−30X−+20Y=−5

             −2Y=1

∴Y=−21

On putting Y=−21 in (i), we get

5X+3×−21=1⇒5X=25⇒X=21

∴x=X1
