Question

find the three different solutions of the each of the following equations 1. 3x+4y=7 2. y=6x

Answer 1

3x+4y=7
4y=7-3x
If x=1 then
4y=7-3×1
4y=7-3
4y=4
Y=0

If x=2 then
4y=7-3×2
4y=1
y=0.25

If x= -1 then
4y=7-3×(-1)
4y=7+3
4y=10
y=2.5

2. Y=6x
If x=1 then
Y=6×1
Y=6

If x=2 then
Y=6×2
Y=12

If x= -1 then
Y=6 (-1)
Y= -6
