Question

Solve the Equation -21 = 1/2c - 11

Answer 1

Answer:

c = -20

Step-by-step explanation:

-21=1/2c-11

-21+11=1/2c

-10=1/2c

-10*2=c

-20=c

Answer 2

Answer:

c = - 20

Step-by-step explanation:

Given

- 21 = $\frac{1}{2}$ c - 11 ( add 11 to both sides )

- 10 = $\frac{1}{2}$ c ( multiply both sides by 2 to clear the fraction )

- 20 = c , that is

c = - 20
