Question

value of k.
2. Find the number of solutions of the following pair of linear equations:
x + 2y - 8 = 0
2x + 3y = 16​

Answer 1

Answer:

multiply the first equation by 2,

2(X+2y-8)= 2x+4y-16=0

write the second equation in standard form

2x+3y-16=0

subtracting the second equation by the first equation,

y=0

now put y=0 in first equation

X+2(0)-8=0

X+0-8=0

X=8

therefore, X=8 and y=0
