Question

Solve y=3x and y-x=26 and hence find the value of m such that y=mx+13 

a) m=2

b) m=3

c) m=1

d) none of these


​

Answer 1

Step-by-step explanation:

given,

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

y-x=26

y=26+x

substituting (1){y=3x}

3x=26+x

3x-x=26

2x=26

x=26/2

x=13

from(1)

y=3x

y=3(13)

y=39

now, y=mx+13

39=m(13)+13

39=13m+13

-13m=13-39

-13m=-26

m=-26/-13

m=2
