To solve the equation 2 x 20 = 15 – 3 x, we first need to clarify what the equation states. This is an algebraic equation where we have a variable, x, that we need to isolate in order to find its value.
Let’s break down the equation step by step:
- Start with the original equation: 2x imes 20 = 15 – 3x
- Multiply to simplify the left side: 40x = 15 – 3x
- Next, we want to get all the x terms on one side of the equation. To do this, add 3x to both sides: 40x + 3x = 15
- This simplifies to: 43x = 15
- Now, divide both sides by 43 to isolate x: x = 15 / 43
Therefore, the value of x is 15/43 or approximately 0.349.
This solution shows how to manipulate algebraic expressions to isolate the variable and find its value.
