Question

Good Afternoon.

Solve the following simultaneous equation graphically :

3x - 4y = -7 ; 5x - 2y = 0

Answer 1

$\huge\underline \color{gold}ANSWER$

3x - 4y = -7 --- (i)

5x - 2y = 0 ---(ii)

(ii) * 2

Subtracting (ii) from (I)

3x - 4y = -7 --- (i)

-10x + 4y = 0 -- (ii)

____________

-7x = - 7

x = 1

Putting the value of x in (ii),

-10 + 4y = 0

4y = 10

y = 5/2
