I'm trying to solve these equations but it seems I didn't get the correct one. please help if you still can.
to solve the equations:
1. 0.4 =32z
2. 8n - 2 = 14
3. 2 (x + 3) = 4
Thanks a lot.
1.
0.4 =32z
0.4/32 = z
0.125 = z
2.
8n - 2 = 14
8n = 16
n = 2
3.
2 (x + 3) = 4
2x + 6 = 4
2x = -2
x = -1
Now, I understand, thank you,thank you very much, Ms. Sue.
You're very welcome, Nima.
To solve these equations, we will go through each one step by step:
1. To solve the equation 0.4 = 32z, we need to isolate the variable z.
To do this, divide both sides of the equation by 32:
0.4/32 = 32z/32
0.0125 = z
So, the solution to the equation is z = 0.0125.
2. To solve the equation 8n - 2 = 14, we need to isolate the variable n.
First, add 2 to both sides of the equation:
8n - 2 + 2 = 14 + 2
8n = 16
Next, divide both sides of the equation by 8:
8n/8 = 16/8
n = 2
So, the solution to the equation is n = 2.
3. To solve the equation 2(x + 3) = 4, we need to distribute the 2 to the terms inside the parentheses.
Multiply 2 by each term inside the parentheses:
2x + 2(3) = 4
2x + 6 = 4
Next, subtract 6 from both sides of the equation:
2x + 6 - 6 = 4 - 6
2x = -2
Finally, divide both sides of the equation by 2:
2x/2 = -2/2
x = -1
So, the solution to the equation is x = -1.
I hope this helps! Let me know if you have any further questions.
