Please hurry i need help 24 points i just put just helpWhich is the best first step when solving the following system of equations? 5 c + 4 d = 10. 3 c + 2 d = 16. Multiply the first equation by Negative 2. Solve for d in the second equation. Solve for c in the first equation. Multiply the second equation by Negative 2.

Multiply the second equation by Negative 2.

Step-by-step explanation:

5 c + 4 d = 10.

3 c + 2 d = 16.

I would multiply the second equation by -2 so that the coefficient for d is the opposite in each equation.  That way we can add the two equations together and eliminate d.

5 c + 4 d = 10.

-6 c + -4 d = -32

-c                  = -22

Multiply the second equation by Negative 2.

Step-by-step explanation:

5c + 4d = 10

3c + 2d = 16

5c + 4d = 10

-6c - 4d = -32

-c = -22

c = 22

the answer to the expression is 83

c is the answer
