Question

solve 3x+2y-5 and find the value of x and y​

Answer 1

Answer:

3

x

−

2

y

=

5

and

x

=

y

+

2

If we substitute

(

y

+

2

)

for

x

, we get:

3

(

y

+

2

)

−

2

y

=

5

=

3

y

+

6

−

2

y

=

5

Now we must collect the like terms to get

y

on its own:

y

=

−

1

Now that we know the value of

y

, we can solve for

x

x

=

y

+

2

=

−

1

+

2

=

1

Just to make sure, we should plug our values back into one of the equations to check that we obtained the correct answer.

Answer 2

Answer:

3x +2y-5

y= 5-3x

-------. put this equation in 1

2

3x+2(5-3x) -5

--------

2
