What is the value of n in the equation 0.2 (n - 6) = 2.8?

(1) 8 (3) 20

(2) 2 (4) 44

So,

0.2 (n - 6) = 2.8

Distribute.

0.2n - 1.2 = 2.8

Add 1.2 to both sides.

0.2n = 4

Divide both sides by. 2.

n = 20

Check.

0.2 (20 - 6) = 2.8

Simplify inside parentheses.

0.2 (14) = 2.8

Multiply.

2.8 = 2.8 This checks.

S = {2.8}
