Question

solve the simultaneous eqution 13x-6y=20,7x+4y=18​

Answer 1

Answer:

Y=1

X =2

Step-by-step explanation:

13x - 6y = 20 - - > 1

7x + 4y = 18 - - > 2

Now multiple the equation 1 with 7 and equation 2 with 13

So we will get following equation

91x - 42y = 140

91x + 52y = 234

- - -

- 94y = -94

Y =1

Puting the value of y in equation 1 then we will get

X=2
