Answer 3

Let's solve the equations step by step:

B) To solve the equation 1024÷(12+4x)-25=7, we'll follow these steps:

1. Simplify the equation: 1024 ÷ (12 + 4x) - 25 = 7

2. Move the constant term to the other side: 1024 ÷ (12 + 4x) = 7 + 25 1024 ÷ (12 + 4x) = 32

3. Multiply both sides of the equation by (12 + 4x) to eliminate the fraction: 1024 = 32(12 + 4x)

4. Distribute the multiplication on the right side: 1024 = 384 + 128x

5. Move the constant term to the left side and the variable term to the right side: 1024 - 384 = 128x 640 = 128x

6. Divide both sides of the equation by 128 to solve for x: x = 640 ÷ 128 x = 5

Therefore, the solution to the equation is x = 5.

G) To solve the equation 35(2x + 99)5³ = 3800, we'll follow these steps:

1. Simplify the equation: 35(2x + 99)5³ = 3800

2. Evaluate the exponent on the left side: 35(2x + 99)125 = 3800

3. Divide both sides of the equation by 125 to isolate the parentheses: 35(2x + 99) = 3800 ÷ 125 35(2x + 99) = 30.4

4. Divide both sides of the equation by 35 to solve for (2x + 99): 2x + 99 = 30.4 ÷ 35 2x + 99 = 0.8685714

5. Subtract 99 from both sides of the equation: 2x = 0.8685714 - 99 2x = -98.1314286

6. Divide both sides of the equation by 2 to solve for x: x = (-98.1314286) ÷ 2 x = -49.0657143

Therefore, the solution to the equation is x = -49.0657143.
