Question

Plz tell x-2y=4,2x-y=10 x value and y value

Answer 1

Step-by-step explanation:

=x-2y=4-----1

=2x-y=10------2

=equation 1 ×2

=2x -4y =

Answer 2

2 × (x - 2y = 4)

2x - y = 10

____________

2x - 4y = 8----(1)

2x - y = 10------(2) [using elimination method]

----------------

- 3y = -2

y = $\frac{2}{3}$ ...ans....

Now, put above value of y in equ-----(2)

2x - $\frac{2}{3}$ = 10

2x = 10 - $\frac{2}{3}$

2x = $\frac{30-2}{3}$

x = $\frac{30-2}{3}$ ×$\frac{1}{2}$

x = $\frac{28}{6}$

x = $\frac{14}{3}$ ...ans....
