Answer 3

To solve the linear equation $4(5-x) = 3x-1$, we need to find the value of $x$ that satisfies the equation. Here's how you can do it step-by-step:

Step 1: Distribute the multiplication on the left side of the equation: $4 \cdot 5 - 4 \cdot x = 3x - 1$

Step 2: Simplify the equation by combining like terms: $20 - 4x = 3x - 1$

Step 3: Get all $x$ terms on one side of the equation and the constants on the other side. To do this, let's add $4x$ to both sides of the equation and add $1$ to both sides as well: $20 - 4x + 4x + 1 = 3x + 4x - 1 + 1$

Step 4: Simplify further: $21 = 7x$

Step 5: Finally, to solve for $x$, divide both sides by $7$: $x = \frac{21}{7}$

Step 6: Simplify the fraction: $x = 3$

So, the solution to the linear equation is $x = 3$.
