Answer: x = -7/2.

Explanation:

Step 1: Distribute the 3 to both terms inside the parentheses:

-2(x + 5) - 4 = -7

Step 2: Simplify the expression by multiplying:

-2x - 10 - 4 = -7

Step 3: Combine like terms on the left side:

-2x - 14 = -7

Step 4: Isolate the variable term by adding 14 to both sides:

-2x - 14 + 14 = -7 + 14

-2x = 7

Step 5: Solve for x by dividing both sides by -2:

(-2x) / -2 = 7 / -2

x = -7/2

Therefore, the solution to the equation is x = -7/2.
