Answer 2

Answer:

a=1/3and b=2/3

Step-by-step explanation:

Your question:-

To find value of 'a' and 'b' with substitution method.

Your solution:-

6a+3b=4 (equation-1).

a+b=1 (equation-2)

Using equation (2):-

a+b=1

b=1-a (equation-3)

Now substituting value of b=1-a in equation (1):-

6a+3b=4

6a+3(1-a)=4

6a+3-3a=4

3a=4-3

3a=1

a=1/3 (equation-4)

Now substituting value of a=1/3 in equation (3)

b=1-a

b=1-1/3

b=3-1/3

b=2/3

Therefore value of a=1/3 and value of b=2/3.
