Answer 2

It looks like you've provided three different linear equations. To help you out, I can solve each of them for the variable "x".

а) $3x - 7.5 = 0$:

First, add 7.5 to both sides to isolate the term with "x": $3x = 7.5$

Now, divide both sides by 3 to solve for "x": $x = \frac{7.5}{3} = 2.5$

So, the solution for this equation is $x = 2.5$.

b) $7x - 11 = 4 + 2x$:

First, subtract $2x$ from both sides to move all terms with "x" to one side: $5x - 11 = 4$

Next, add 11 to both sides: $5x = 15$

Finally, divide both sides by 5 to find the value of "x": $x = \frac{15}{5} = 3$

The solution for this equation is $x = 3$.

c) $2(3x - 2) = 8 - (2x + 4)$:

First, distribute the 2 on the left side of the equation: $6x - 4 = 8 - 2x - 4$

Combine the constants on the right side: $6x - 4 = 4 - 2x$

Add $2x$ to both sides: $8x - 4 = 4$

Add 4 to both sides: $8x = 8$

Finally, divide both sides by 8: $x = 1$

So, the solution for this equation is $x = 1$.
