Answer:
The correct option is 1.
Step-by-step explanation:
The given set of equations is
Equation A: c = 2d + 1
Equation B: c = 3d + 5
Using equation A and equation B, equate the value of c.
\(2d+1=3d+5\)
\(1-5=3d-2d\)
\(-4=d\)
The value of d is -4. So the value of c is
\(c=2d+1=2(-4)+1=-7\)
The equation 2d+1=3d+5 is used to find the solution to the set of equations, therefore the correct option is 1.
