Question

How do I use substitution to find the solution of the system of equations c+3d=8 and c=4d−6?

Answer 1

c+3d=8

c=4d-6

4d-6+3d=8

7d=14

d=2

And c=2

Answer!!

Answer 2

Answer:

Since value of c is already given so:-

C+3D=8. (Substitute c in equation)

4d-6+3D=8

7d=14

Value of d is 2
