Question

solve 5+7x+2y-8(3-4x-3y)​

Answer 1

Given equations are:

x+2y=5      .(1)

7x+3y=13    .2)

Multiplying equation (1) by 7

7x+14y=35    3)

Subtracting equation (2) from equation (3), we have

11y=22

y=2

Now putting y value in equation (1) 

⇒x+2(2)=5

⇒x=5−4

⇒x=1

x=1,y=2

Answer 2

Given equations are:

x+2y=5 (1)

7x+3y=13 (2)

Multiplying equation (1) by 7

7x+14y=35 (3)

Subtracting equation (2) from equation (3), we have

11y=22

y=2

Now putting y value in equation (1)

⇒x+2(2)=5

⇒x=5−4

⇒x=1

x=1,y=2
