Question

3-(x-y)=y+2 ,2 (x+5)=4-3y​

Answer 1

Answer :-

We pick either of the equations and write one variable in terms of the other.

Let us consider the equation 3−(x−5)=y+2 and write it as

3−x+5=y+2

or −x−y=−6

or x+y=6

or y=6−x...........(1)

Now the equation 2(x+y)=4−3y can be rewritten as:

2x+2y=4−3y

or 2x+5y=4

Substitute the value of y in the equation 2x+5y=4. We get

2x+5(6−x)=4

i.e. 2x+30−5x=4

i.e. −3x=−26

i.e. x=

Therefore, x=

Substituting this value of x in equation 1, we get

y=6−
