Question

`\sf 3c+ (-2) = -20`

Answer 1

Explanation:

Ok.

1. We need to isolate the variable on the left side of the equation by sending the -2 across the equal sign. Remember if a number or variable goes over equal they are opposite!

3c= -20+2

3c=-18

2. Isolate c as the only variable on the left of equation!

c=-18/3

c=-6

3. Always double check answers!

-18-2=-20

TRUE

Answer: c=-6

Answer 2

c = -6

Explanation:

Given equation,

→ 3c + (-2) = -20

Then the value of c will be,

→ 3c + (-2) = -20

→ 3c - 2 = -20

→ 3c = -20 + 2

→ c = -18/3

→ [ c = -6 ]

Hence, the value of c is -6.
