-2x - 18 = 611-2x) + 4x

x = (-629)/4

Step-by-step explanation:

Solve for x:

-2 x - 18 = 4 x - 2 x + 611

4 x - 2 x = 2 x:

-2 x - 18 = 2 x + 611

Subtract 2 x from both sides:

(-2 x - 2 x) - 18 = (2 x - 2 x) + 611

-2 x - 2 x = -4 x:

-4 x - 18 = (2 x - 2 x) + 611

2 x - 2 x = 0:

-4 x - 18 = 611

Add 18 to both sides:

(18 - 18) - 4 x = 18 + 611

18 - 18 = 0:

-4 x = 611 + 18

611 + 18 = 629:

-4 x = 629

Divide both sides of -4 x = 629 by -4:

(-4 x)/(-4) = 629/(-4)

(-4)/(-4) = 1:

x = 629/(-4)

Multiply numerator and denominator of 629/(-4) by -1:

x = (-629)/4
