1 answer

To solve the equation

\[ -3(4x - 2) + 5x + 4 = -18, \]

we first distribute the \(-3\) across the terms in the parentheses:

\[ -3 \cdot 4x + -3 \cdot (-2) = -12x + 6. \]

Now substitute this back into the equation:

\[ -12x + 6 + 5x + 4 = -18. \]

Next, combine like terms. The \(5x\) and \(-12x\) combine as follows:

\[ -12x + 5x = -7x. \]

And the constants \(6\) and \(4\) combine to give:

\[ 6 + 4 = 10. \]

Putting it all together, we have:

\[ -7x + 10 = -18. \]

Now, isolate \(x\) by first subtracting \(10\) from both sides:

\[ -7x + 10 - 10 = -18 - 10, \]

which simplifies to:

\[ -7x = -28. \]

Next, divide both sides by \(-7\):

\[ x = \frac{-28}{-7} = 4. \]

Thus, the solution is:

\[ \boxed{4}. \]
