Solve for X in the Linear Equation: 3x+5=2x+20

Question

Solve for X:

3x+5=2x+20 3x+5=2x+20

Step-by-Step Solution

To solve the equation 3x+5=2x+20 3x + 5 = 2x + 20 , we need to find the value of x x that satisfies this equation. Here are the detailed steps:

  • Step 1: Eliminate the variable from one side.
    We want to get all terms involving x x on one side and constant terms on the other side. First, subtract 2x 2x from both sides of the equation to eliminate x x from the right side.

    3x+52x=2x+202x 3x + 5 - 2x = 2x + 20 - 2x

    This simplifies to:

    x+5=20 x + 5 = 20

  • Step 2: Simplify the equation.
    Now, we need to isolate x x by removing the constant term from the left side. Subtract 5 from both sides:

    x+55=205 x + 5 - 5 = 20 - 5

    This simplifies to:

    x=15 x = 15

  • Step 3: Verify the solution.
    Substitute x=15 x = 15 back into the original equation to check if it holds true:

    3(15)+5=2(15)+20 3(15) + 5 = 2(15) + 20

    This results in:

    45+5=30+20 45 + 5 = 30 + 20

    50=50 50 = 50

    Since both sides of the equation are equal,x=15 x = 15 is indeed the correct solution.

Therefore, the solution to the equation 3x+5=2x+20 3x + 5 = 2x + 20 is x=15 x = 15 .

Answer

15 15
