Question

Hey guys
how are you all
how are you my cutie pie
Solve for X and y :
(I) y+7/5 = 2y-x/4 + 3x-5
7-5x/2 + 3-4y/6 = 5y-18
please solve it ​

Answer 1

Given equations are, 

5y+7=42y−x+3x−5

⇒4(y+7)=5(2y−x+12x−20)

⇒4y+28=10y+55x−100

⇒55x+6y=128 ....(1)

and 27−5x+63−4y=5y−18

⇒3(7−5x)+(3−4y)=6(5y−18)

⇒21−15x+3−4y=30y−108

⇒15x+34y=132 ....(2)

Multiply (1) by 3 and (2) by 11, we get

165x+18y=384

165x+374y=1452

Subtracting above equations we get

356y=1068⟹y=3

Put value of y in (1)

we get x=2

∴x=2,y=3
