Question

solve the simultaneous equations graphically represented 3x - 4y = -7 ; 5x - 2y = 0​

Answer 1

Answer:

x=1 , y=2

Step-by-step explanation:

3x - 4y = -7 -----(1)

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

Now multiply by 2 in equation (2)

=>10x -4y =0

Now subtract eqn (1) from (2)

=>-7x = -7x

=> x = 1

Now put the value of x in eqn (1)

we get,

=> 3×1 - 4y = -7

=>3- 4y = -7

=>-4y = -10

=> y = 5/2. Ans.
