Answer 3

To solve the equation, we need to find the value of 'x' that makes both sides of the equation equal. Let's solve it step by step:

Step 1: Expand and simplify both sides of the equation. On the left-hand side (LHS): 3(2x - 1) - 5(x + 1) = 6x - 3 - 5x - 5 = (6x - 5x) + (-3 - 5) = x - 8

So the equation becomes: x - 8 = 3x + 4

Step 2: Move all the 'x' terms to one side of the equation and the constant terms to the other side. Subtract 'x' from both sides: x - x - 8 = 3x - x + 4

Simplify: -8 = 2x + 4

Step 3: Isolate 'x' on one side of the equation. Subtract 4 from both sides: -8 - 4 = 2x + 4 - 4

Simplify: -12 = 2x

Step 4: Solve for 'x'. To find 'x', divide both sides by 2: x = -12 / 2 x = -6

So, the solution to the equation is x = -6. You can check this solution by substituting 'x' back into the original equation to see if both sides are equal.
