Answer: x = -1

Step-by-step explanation:

The problem is asking you the sum (+) of 3 times of a unknown number (let the unknown number be x) and 7, as in 3x + 7

According to the problem this expression is equal to 4,

3x + 7 = 4

1. Subtract 7 from both sides

3x = -3

2. Divide 3 on both sides

x = -1

Your final answer would be negative 1
