Question

Solve the simultaneous equation :-

3x - y =5
4x - 3y = -1.

Hence, find p , if y = px - 3. ​

Answer 1

3x - y =5
4x - 3y = -1.

4(3x-y)=(5)4
3(4x-3y)=(-1)(3)

12x-y=20.........(1)
12x-9y=-3.........(2)

subtract 1 from 2
-8y=-23
y=23/8
px-3=23/8
p=$\frac{23}{8x}$+3



p=$\frac{23+24x}{8x}$
