Question

If x+y=3 and 3x+2y=4 the value of negative of x is
​

Answer 1

Answer:

-2

Step-by-step explanation:

x+ y = 3 ...........( i )

3x+2y = 4 ....... (ii)

by multiplying 3 both sides eq (iii)

We get 3x+3y = 9 ....(iv)

now eq (iii) substrat from eq (ii)

we get

3x+3y - (3x+2y) =9-4

=3x+3y-3x-2y = 5

=y=5

then substitute the value of y in eq (i)

We get x+5 =3

= x= 3-5

= x = -2
