Answer 3

Let's solve each of the equations step-by-step:

1. $4(2x-6) = 4x-4$

First, distribute the 4 on the left side of the equation:

$8x - 24 = 4x - 4$

Next, move all the terms containing $x$ to one side by subtracting $4x$ from both sides:

$8x - 4x - 24 = -4$

Simplify the left side:

$4x - 24 = -4$

Now, isolate $x$ on one side by adding 24 to both sides:

$4x = 20$

Finally, divide both sides by 4 to find the value of $x$:

$x = 5$

2. $-9y + 3 = 3(8y + 45)$

First, distribute the 3 on the right side of the equation:

$-9y + 3 = 24y + 135$

Next, move all the terms containing $y$ to one side by subtracting $24y$ from both sides:

$-9y - 24y + 3 = 135$

Simplify the left side:

$-33y + 3 = 135$

Now, isolate $y$ on one side by subtracting 3 from both sides:

$-33y = 132$

Finally, divide both sides by -33 to find the value of $y$:

$y = -4$

3. $20 + 5x = 44 + x$

First, simplify the equation by combining like terms:

$5x + 20 = x + 44$

Next, move all the terms containing $x$ to one side by subtracting $x$ from both sides:

$5x - x + 20 = 44$

Simplify the left side:

$4x + 20 = 44$

Now, isolate $x$ on one side by subtracting 20 from both sides:

$4x = 24$

Finally, divide both sides by 4 to find the value of $x$:

$x = 6$

So, the solutions to the given equations are:

1. $x = 5$

2. $y = -4$

3. $x = 6$
