Question

Solve for c. 0.2(10-5c)=5c-16
c=

Answer 1

c = -1/5 = -0.200

Explanation:

1

Simplify —

5

Step 2 3.1 Pull out like factors :

10 - 5c = -5 • (c - 2)

Step 3 6.1 Solve : 2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Step 4 6.2 Solve : 5c+1 = 0

Subtract 1 from both sides of the equation :

5c = -1

Divide both sides of the equation by 5:

c = -1/5 = -0.200

Answer 2

c=3

Explanation:

0.2(10-5c)X 10 = 5c X 10-16 X 10

2(10-5c)=50c-160

20-10c=50c-160

20-10c-20=50c-160-20

-10c=50c-180

-10c-50c=50c-180-50c

-60c=-10

-60c/-60=-180/-60

c=3
