Question

Solve by the method of eliminations
X-y=5
3x + 2y =25​

Answer 1

Answer:

From the above equations....

x = 7

y = 2

Answer 2

x−y=5−−−(1)

3x+2y=25−−−(2)

3x−3y=25

3x+2y=25

_______________

+5y=+10

⇒5y=10

⇒y=10 /5

⇒y=2.

sub y=2 in (1)

x−y=5

⇒x−2=5

⇒x=5+2

⇒x=7

∴ x=7  and y=2.
