Question

5x+3y=35; x+2y =14 solve the eqn
​

Answer 1

Answer:

5x +3y =35 ---------(1)

X +2y=14-------------(2)

multiply equation 2 by 5

we get

5x +10y= 70----------(3)

subtract equation 3 from 1

5x+3y=35-------(1)

5x+10y=70---------(3)

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

-7y= -35

y=-35/-7

y=5

put y=5in equation 2

X+2y=14

X+2(5)=14

X+10=14

X=14-10

X=4
