EXPLAIN YOUR ANSWER

5.
A set of equations is given below:

Equation A: c = 2d + 1
Equation B: c = 3d + 5

Which of the following is a step that can be used to find the solution to the set of equations? (5 points)



2d + 1 = 3d + 5
2d = 3d + 5
2d + 1 = 3d
2d + 5 = 3d + 1

Answer 1

The correct answer is 1. 2d + 1 = 3d + 5

Explanation:

Answer 2

Equation A: c=2d+1
Equation B: c=3d+5
2d+1=3d+5
-3d -3d
(subtract three to both sides)
-1d+1=5
-1 -1
(Subtract one to both sides)
-1d=4
(Divide negative one to both sides)
Answer:
d=-4
