Given:
0.2(4n + 3) = 2.2
Let's solve for n:
First Step:
Use distributive property to expand the parenthesis
0.2*4n + 0.2*3 = 2.2
0.8n + 0.6 = 2.2
Second Step:
Subtract 0.6 from both sides
0.8n + 0.6 - 0.6 = 2.2 - 0.6
0.8n = 1.6
Third Step:
Divide both sides by 0.8
ANSWER:
n = 2
Let's confirm the answer:
Input 2 for n in the equation
0.2(4*2 + 3) = 2.2
0.2(8 + 3) = 2.2
1.6 + 0.6 = 2.2
2.2 = 2.2
Since the left side equate the right side, the answer is correct.
