X+1+1+6x>3(x-4)-(x-4)

x > - 2

Step-by-step explanation:

Given

x + 1 + 1 + 6x > 3(x - 4) - (x - 4) ← distribute parenthesis and simplify both sides

7x + 2 > 3x - 12 - x + 4

7x + 2 > 2x - 8 ( subtract 2x from both sides )

5x + 2 > - 8 ( subtract 2 from both sides )

5x > - 10 ( divide both sides by 5 )

x > - 2

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
