Solve 7x + 1 < 4(x - 2). {x | x < 3} {x | x > 3} {x | x > -3} {x | x < -3} (pls i suck at math)

Please leave out "suck at math" comments; such a comment helps no one, least of all you.

7x + 1 < 4(x - 2)
Distribute that multiplier 4:     7x + 1 < 4x - 8
Subtr. 4x from both sides:       3x + 1 < -8
Subtr. 1 from both sides:          3x < - 9
Divide both sides by 3:                x < -3  (answer)

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .
