Question

write two solutionsfor each of the following equations

3x+4y=7

x=6y

Answer 1

For first equation
x=7-4y/3
put y=0
x=7-4×0/3
x=7
again, put y=3
x=7-4×3/3
x=3

Now, for second equation
put y=0
x=6×0
x=0
again, put y=1
x=6×1
x=6

Answer 2

for equation 3x + 4y = 7
let the value of x be 0 and 2
the two solutions are :
3(0) + 4y = 7
4y= 7
y= 4/7
now x=2
3(2) + 4y=7
4y=7-6
y=1/4
for equarion x=6y
let y=1
x=6(1)

x =6(1)
let y=2
x=6(2)
x=12
