Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Apply the distributive property to expand the expression.
  • Step 2: Simplify both sides to isolate the variable.
  • Step 3: Divide to solve for the variable.

Now, let's work through each step:

Step 1: Apply the distributive property
The given equation is 4(6x)+(3x+5)=14 -4(6-x)+(3x+5)=14 .
First, distribute 4-4:
4×6+4×x=24+4x-4 \times 6 + -4 \times -x = -24 + 4x.
Insert this into the equation:
24+4x+3x+5=14-24 + 4x + 3x + 5 = 14.

Step 2: Simplify the equation
Combine like terms (the xx terms and constants):
4x+3x=7x4x + 3x = 7x.
24+5=19-24 + 5 = -19.
So, the equation becomes:
7x19=147x - 19 = 14.

Step 3: Solve for xx
Add 19 to both sides to isolate the xx-term:
7x19+19=14+197x - 19 + 19 = 14 + 19.
7x=337x = 33.
Divide both sides by 7:
x=337x = \frac{33}{7}.
Simplifying this gives x=457x = 4\frac{5}{7}.

Therefore, the solution to the problem is x=457 x = 4\frac{5}{7} .

Answer

457 4\frac{5}{7}
