What value of ww makes the equation below true?

5w+3=
28

3 answers

To solve the equation \( 5w + 3 = 28 \), follow these steps:

  1. Subtract 3 from both sides: \[ 5w + 3 - 3 = 28 - 3 \] This simplifies to: \[ 5w = 25 \]

  2. Divide both sides by 5: \[ w = \frac{25}{5} \] This simplifies to: \[ w = 5 \]

So, the value of \( w \) that makes the equation true is \( w = 5 \).

Which equation has the solution x, equals, x=3?

To create an equation with the solution \( x = 3 \), you can use a simple linear equation. Here are a few examples:

  1. Linear equation: \[ x - 3 = 0 \] This simplifies to \( x = 3 \).

  2. Another linear equation: \[ 2x - 6 = 0 \] When simplified, you get \( 2x = 6 \) and thus \( x = 3 \).

  3. More complex equation: \[ 3(x - 3) = 0 \] Expanding this gives \( 3x - 9 = 0 \), which simplifies to \( x = 3 \) when solved.

Any of these equations will have \( x = 3 \) as a solution.
