Question

How many set of ordered pairs (x,y)
satisfy these two simultaneous
equations ?
8x + 3y = 25
32x + 12y = 100
(a) Zero
(b) One
(c) Two
(d) Infinity
​

Answer 1

Answer:

d) infinity

Step-by-step explanation:

d) infinity

a1x+b1y+c1=0 a2x+b2y+c2=0 are two simultaneous equations

if a1/a2= b1/b2= c1/c2

then the system of linear equations in two variables have infinity solutions

and they are coincident lines
