Step-by-Step Solution

Let's solve the equation 5(2x)+2x=3(4x) 5(2-x) + 2x = 3(4-x) step by step:

First, apply the distributive property to both sides of the equation:

  • Left side: 5(2x)=525x=105x 5(2-x) = 5 \cdot 2 - 5 \cdot x = 10 - 5x .
  • Right side: 3(4x)=343x=123x 3(4-x) = 3 \cdot 4 - 3 \cdot x = 12 - 3x .

Substituting back, the equation becomes:

105x+2x=123x 10 - 5x + 2x = 12 - 3x .

Next, combine like terms on the left side:

103x=123x 10 - 3x = 12 - 3x .

At this point, notice that the terms involving x x on both sides are identical (3x-3x). This means the terms containing x x cancel each other out:

10=12 10 = 12 .

Since 1012 10 \neq 12 , we encounter a contradiction.

This implies that there is no solution to the equation. The given equation represents parallel lines that never intersect, so there is no value of x x that satisfies the equation.

Therefore, the solution to the problem is There is no solution.

Answer

There is no solution.
