Question

(i) 2x + y = 5; 3х - у = 5​

Answer 1

Answer:

x=2

y=1

Step-by-step explanation:

2x + y = 5 (equation 1)

3х - у = 5​ (equation 2)

adding both the equations

2x + y = 5

3х - у = 5​

5x+0=10

5x=10

x=10/5

x=2

sub in equation 1

2(2) + y = 5

4+y=5

y=5-4

y=1

$2x + y = 5.................(eq.1)$

$3x - y = 5.................(eq.2)$

By using eliminating method (+y) and (-y) would be cancelled

$2x + 3x = 5 + 5$

$5x = 10$

$x = \frac{10}{5}$

$x = 2$

By putting the value of x in (eq.1),we get :-

$2x + y = 5$

$2(2) + y = 5$

$4 + y = 5$

$y = 5 - 4$

$y = 1$
